INTRODUCTION

Please note, to assist TR Engineering in improving customer

service, it is important that the guarantee/registration card is

completed and returned.

The Activair is a single component unit air source heat

pump, designed to provide hot water or low-temperature

heating by extracting heat energy from the surrounding air.

The Activair has been designed and constructed to give

years of trouble-free service, and these instructions are

provided to assist you in obtaining the best performance with

the least trouble and cost.

OPERATING INSTRUCTIONS

The appliance is controlled via the remote programmer

included with the unit. This can be situated anywhere in the

property, enabling management of the settings without

having to access the main unit.

Before starting the appliance, ensure that it has been

installed in full accordance with these instructions and that

all necessary safety checks have been carried out.

The diagram below (fig. 1) shows the programmer layout with

the controls uncovered (lift off the protective flap).

SETTING THE CLOCK

Before starting the appliance, the clock should be set to enable

control of the heat pump via the timer.

Note: the appliance operates on a 24-hour clock only.

Ensuring the programmer is on standby (LCD screen will not be

illuminated), press the CLOCK button once. The first pair of

digits in the clock display will begin to flash. Press the CLOCK

ADJUSTMENT buttons (+/-) until the current hour is set.

Press the CLOCK button once more; the second pair of digits in

the clock display will begin to flash. Press the CLOCK

ADJUSTMENT buttons (+/-) until the minutes past the hour are

set.

To return to standby mode, repeatedly press the CLOCK button

until the current time is displayed in full.

FIG 1

SETTING THE TIMER

Using the timer, it is possible to set two separate time periods

at which the appliance will operate.

Ensuring the programmer is on standby (LCD screen will not

be illuminated), press the CLOCK button three times. The first

pair of digits on the clock display will flash and the timer

settings display will read ‘ON’. The number immediately below

this will indicate that programme #1 is currently being

modified.

Press the TIMER ADJUSTMENT buttons (+/-) until the time is

set to the hour you wish the appliance to start.

Press the CLOCK button; the second pair of digits in the clock

display will begin to flash. Adjust in the same way to set the

minutes past the hour.

Press the CLOCK button and set the hour you wish the

appliance to cease operation. Press the CLOCK button once

more and set the minutes past the hour.

To return to standby mode, repeatedly press the CLOCK

button until the current time is displayed. To set a second

programme, instead press the CLOCK button once.

The first pair of digits on the clock display will flash and the

timer setting display will read ‘ON’. The number immediately

below this will indicate that programme #2 is currently being

modified.

Use the TIMER ADJUSTMENT buttons (+/-) as described

above to set the second programme. After setting the minutes

past the hour, press the CLOCK button once to return to

standby mode.

To activate the programme(s), press the TIMER ON/OFF

button once. The timer status display will read ‘1’.

The Activair should now cut in and out according to the times

set. The running indicator will display the SUN symbol

whenever the appliance is operating.

Please note that during the time periods at which the

appliance is set to operate, it will not do so constantly. When

the cylinder water temperature has reached the required level,

the heat pump will cease operation until the water has cooled

or has been used. During these periods, the SUN symbol will

flash in the running indicator display.

Please ensure that all other required parameters, such as

cylinder water temperature (see adjacent column), have been

set before operating the appliance.

To cease operation in this mode, press the TIMER ON/OFF

button once. The timer status display will read ‘0’ and the

appliance will return to non-timed control mode.

NON-TIMED CONTROL

It is possible to operate the appliance without using the timer

control. Ensure that the clock and all other required parameters

have been set before continuing.

Ensure the timer status display reads ‘0’ and press the ON/OFF

button at the top right of the programmer. The LCD display and

power indicator light will illuminate and the appliance will start.

The running indicator will display the SUN symbol whenever the

appliance is operating.

The appliance will now run until the required cylinder water

temperature is reached, at which time the SUN symbol will flash

in the running indicator display.

Please ensure that all other required parameters, such as

cylinder water temperature (see below), have been set before

operating the appliance.

To cease operation in this mode, press the ON/OFF button

once. The LCD screen and power indicator light will fade.

SETTING THE WATER TEMPERATURE

The appliance can be set to heat water between a range of

40°C and 55°C, depending upon your preference. The water

temperature can be adjusted at any time, whether the heat

pump is running or inactive.

To set the cylinder water temperature, press the

TEMPERATURE ADJUSTMENT buttons (+/-). The temperature

display will change accordingly, before returning to displaying

the current cylinder water temperature.

When the cylinder water temperature has reached the required

level, the appliance will cease to operate until the water in the

cylinder has been used or has cooled.

OPERATING INSTRUCTIONS

(continued)

OPERATING PARAMETER DISPLAY

In certain circumstances, the unit may enter a temporary

lockout mode in order to maintain efficient operation. During

such times, a code will appear on the programmer display (fig.

1). This is entirely normal and the unit will automatically

resume functioning once it has completed its reset cycle.

In the unlikely event the appliance does not resume operation,

full descriptions of the operating parameters and their causes

can be found on page 25.

FROST PROTECTION

As the appliance may be fitted externally to the property being

heated, the water in the system may be in danger of freezing

in very cold weather. As such, the Activair has frost protection

which will bring the heat pump on should the temperature drop

too low. However, to provide protection in the event of a power

outage, a suitable antifreeze should be added to the system.

DEFROST MODE

If the temperature is cold enough for ice to develop on the coil,

this may become clogged and cause the appliance to cease

operation. Should this occur, the unit will automatically enter

defrost mode. This will divert heat from the heating circuit back

to the coil until the ice has melted. The DEFROST symbol will

appear above the temperature display (see fig. 1) during such

times.

PRESSURE SWITCH

Should the refrigerant pressure within the appliance reach too

high a level, the unit will automatically switch off until the

pressure has been reduced, whereupon the unit will restart

automatically. Please note that the unit may take several

minutes to restart after the pressure switch has operated.

Refer to the operating parameter descriptions, page 25, for

further details.

AMBIENT TEMPERATURE CUTOUT

Should the ambient temperature around the appliance reach

too high a level, the unit will automatically switch off until the

temperature has been reduced, whereupon the unit will restart

automatically. Please note, that the unit may take several

minutes to restart after the cutout has operated.

Refer to the operating parameter descriptions, page 25, for

further details.

COIL TEMPERATURE CUT-OUT

Should the coil temperature reach too high a level, the unit will

automatically switch off until the temperature has been reduced,

whereupon the unit will restart automatically. Please note that

the unit may take several minutes to restart after the cut-out has

operated.

Refer to the operating parameter descriptions, page 25, for

further details.

COMPRESSOR OUTLET TEMPERATURE CUTOUT

Should the compressor outlet temperature reach too high a

level, the unit will automatically switch off until the temperature

has been reduced, whereupon the unit will restart automatically.

Please note that the unit may take several minutes to restart

after the cut-out has operated.

Refer to the operating parameter descriptions, page 25, for

further details.

SHUTTING DOWN FOR LONG PERIODS

If power to the heat pump is shut down for a long period during

very cold weather, it is advisable to completely drain the system.

However, too frequent draining of the system should be

avoided, especially in hard water areas, as this could lead to the

build-up of scale in any heating circuit.

SERVICING

While it is not necessary to carry out an annual service on the

appliance, regular inspections may be required, depending upon

where the unit is sited. Full details can be found on page 24.

SIMPLE FAULT-FINDING

If the appliance fails to start for no apparent reason, carry out

the following checks before referring to the operating parameter

and fault-finding guide (page 25/26), or calling your service

engineer:

1. The unit may be running through a process to clear an

operating parameter condition. In most cases, this will be

cleared automatically, though if it persists, check the

programmer display (fig. 1) for an operating parameter

number. Refer to the guide on page 25 for full descriptions

and remedies.

2. Ensure there is a current ‘heat demand’ from the

programmer. Ensure the programmer clock and timer

controls have been set in accordance with the instructions

on pages 6/7 or that it is switched on (if in non-timed mode).

3. Check for failure in the electrical supply.

4. Check for a blown fuse. If the fuse has blown and the

replacement also fails, switch off the mains electrical supply

to the appliance and contact your service engineer.

5. Check the circuit breaker (if fitted). If this has tripped, reset

and restart the appliance. If the circuit breaker trips for a

second time soon after, switch off the mains electrical supply

to the appliance and contact your service engineer.

Note: if the appliance has been shut down due to a failure of the

power supply, the programmer contains a battery backup, which

will allow the preservation of all settings and timings.

If the appliance is operating, but the water temperature is lower

than expected:

1. Check that all isolation valves are fully open.

2. Check the water temperature setting is not too low. This

can be increased by following the instructions on page 7.

3. Check that the vents on the back of the unit and the coil

have not become blocked, impeding the air flow.

4. Check the unit has not entered defrost mode (the DEFROST

symbol will appear above the temperature display –see fig.

1). Should this occur, the heat output from the appliance will

be diverted to the coil, until any ice build-up has been

removed.

5. Ensure there is no air trapped in either the Activair or the

heating/hot water system (page 24).

If sounds are heard from the appliance which sound like the

passage of water, this is merely the normal movement of the

refrigerant within the unit.

If there is power to the appliance and the programmer is

providing a 'heat demand’ to the unit, yet the unit has not

entered running mode (the SUN symbol has not appeared

above the temperature display), it may be that one of the safety

cut-outs (see page 8) has operated. These will typically take

several minutes to clear before the unit restarts.

Other Checks

Ensure the default system settings have not been altered.

These are accessed by holding in the SEARCH button for five

seconds when the programmer is switched off. These are

factory-set and should not require adjustment.

Setting 1 - Factory-set at 26.

Setting 2 - Factory-set at 18.

Setting 3 - Factory-set at 14.

These settings should not be altered from the above without the

express permission of Trianco.

If for some reason the settings do not match the figures given

above, alteration is made via the TEMPERATURE

ADJUSTMENT buttons (+/-).

TIPS FOR IMPROVING PERFORMANCE AND EFFICIENCY

1) Unit maintenance has a dramatic impact upon system performance and service life. Ensure regular inspections are

carried out over the lifetime of the appliance. Dirty coils and fans reduce airflow through the system, resulting in

decreased performance. Regular checks should be carried out to ensure the cleanliness of these components. Refer

to page 24 for details.

2) Programme the appliance to operate at times when the surrounding ambient temperature is at its highest (e.g. noon).

A thermal store may be employed to allow the retention of hot water at this time for later use.

3) If installed externally to the property being heated, the unit should be protected from high winds, as this can lead to

reduced airflow and efficiency, and also cause frost problems; though avoid siting in areas where the airflow is too

restricted, resulting in recirculation of air over the coil.

4) Well-insulate the pipework to and from the appliance to retain as much heat as possible.

5) Where possible, subscribe to economy electricity tariffs (contact your electricity supplier for more information).

6) Lower temperature settings will reduce the amount of energy consumed by the unit.
