required language from the selection.

Standard Terms

Self Learning Optimisation is a system whereby the Heatmiser Control will automatically calculate the

start up time to ensure the building is up to temperature for the programmed switching time. It does this by

monitoring the internal temperature readings, so that for example, in milder weather conditions heat up times

are reduced - thus saving energy.

Preheat is the number of hours the control can come on before the programmed switching time (when in

optimising mode) This is setup under the Engineers code and can be set to no more than 8 hours.

Rate of Change is the time it takes to raise the building by 1.0°C. The factory default for this setting is 20

minutes but the control will automatically adjust this according to the fabric of the building.

Override Using the override button on the Heatmiser keypad allows the user to override the zone for a selected

number of hours, to allow for unscheduled use of the system. A maximum can be set to stop users entering

long override periods.

Switching period status:

• Day is when the control is being controlled to an actual switching time (For example between 07.00

- 17.00 the control would be in a DAY condition) Outside of these hours the control would be in a

night condition.

• Night is when no switching times have been programmed. At these times the control is set back to

the night temperature.

Heater Lockout and Reset is standard on the Heatmiser Mistral and allows for a signal to be fed into the

Heatmiser from the heater when the heater goes to lockout (overheat etc) Once the fault on the heater has

been rectiﬁed a reset signal can be sent to the heater resetting lockout status.

Normal RUN Mode is when the control is operating normally and is not being programmed (ie showing

the time and date screen). It is important to remember that when any alterations have been made to the

Heatmiser’s program, the RUN button is pressed to return the control to the RUN mode.

Normal RUN Mode

There is one main Normal (Run) mode screen, and one Info screen on the Heatmiser IQ+. These are explained

below;

On/Off RUN mode screen

This screen shows the time, actual temperature and the heat relay status (On or Off)

High/Low RUN mode screen

This screen shows the time, actual temperature and the heat status of both high and low ﬂame

Pressing the Information button followed by option 1 will show the following display:

This display is shows the target temperature along with the

switching period status.

Override

The Heatmiser IQ+ can be overridden into a day or night condition to allow for any unscheduled operation

of the system. The maximum time that the unit can be overridden will have been set by the installer.

To program an override period

• From the Normal RUN mode

Press the Override button and enter your security code if required.

• Then choose 1) to enter the override mode

• Then select either 1 or 2 to override the zone

ON(1) or OFF(2)

• You are now prompted to enter the length of the override period.

• Should the zone be above temperature, the control will show the

following screen. Remember that the override function only overrides

time and not temperature. This error message will also appear if the

override time programmed exceeds the maximum override setting

• The status screen then indicates the zone has been

put into an override condition.

To cancel an override period repeat the steps above, choosing 2 for

OFF and then reduce the length of the override period to 00

Summer Mode

To enable the Summer mode facility press the Override/Summer button and select 2 for summer.

The control is then put in to the summer mode, which means that the temperature is controlled to the Night

setback setting.

To cancel repeat the above operation.

Date

To display the current time and date:

• Press INFO

• Press 2 for date.

• To cancel, repeat the above operation.

Heater Lockout/Reset

A supply can be wired into the Heatmiser from the heater lockout connection allowing for remote indication

of a fault. Once the fault has been rectiﬁed on the heater, pressing RESET on the keypad sends a reset signal

to the heater to clear the lockout status. This feature is highly beneﬁcial on heaters installed out of reach.

Heater Reset (No lockout indication)

On heaters where there is no heater lockout, the Heatmiser can be used to send a reset signal.

To send a Reset signal in the case:

• Press the Info/Reset button

• Press 3 for Reset

The reset relay will be energised for a second.

Manual Summer Fan

Providing the installed heaters are equipped with a summer fan facility, the Heatmiser can enable the fan

to give ventilation in summer months.

• Pressing the FAN key displays the following screen.

• At this point you must press ENTER or if you wish to abort this operation pres the DELETE key.

To disable the fan, repeat the above operation.

If the FAN key does not operate, the fan output is being used to give constant or automatic summer fan

control. This is described later in this manual.

Program Mode

From the Normal (RUN) mode screen, pressing the PROG

button will display the following screen.

Before you can access the Heatmiser you must enter the passcode. This passcode is set to 0000 as a factory

default but may be changed at any time by the user to ensure security. This process is explained under

section 4 (code).

Temp

This section is used to changed the temperature settings.

Pressing 1 for Temp displays the following screen:

• You are now prompted to enter the required temperature for the

DAY periods (EG:22.0). This must be entered as three digits.

• When complete, press Enter

• You are now able to select whether you require frost protection.

Selecting ON enables you to set a NIGHT setback temperature.

• Press Enter when you have set the required night

temperature.

If S.Fan has been enabled, you are prompted to enter the summer fan

temperature. The summer fan temperature is calculated by a differential

setting. For example a differential of 03 means that the summer fan

temperature will be 03°C above the day setting. Therefore there is no risk

of the DAY temperature being higher than the Summer Fan setting.

Data

The DATA section is where you are able to set the daily switching periods. There are 3 switching periods per

day available.

• Press PROG and enter the security code

• Now select 2 to enter the DATA menu.

You can see on screen now that we are prompted to enter the switching

period 1 for Monday. So using 24 hour clock notation, enter the required

start time. (EG: 08.00)

Now press enter to accept the Start time and to move the cursor to the end time setting.

We are able to program the required End time, for example 17.00. Don’t forget to use 24 hour clock notation.

When complete, press Enter to accept the programmed switching time and to move onto period 2 Monday.

Programming further periods

You are now able to program period 2 Monday in just the

same way. Press Enter when complete.

Should you not require all three switching periods, simply leave the

times at HH:MM and this period will be ignored.

At this point press the Enter key to move onto Tuesday’s switching periods.

You are able to enter the switching periods for Tuesday

In just the same way.

Should the switching periods be the same on Tuesday, you can press the COPY button and this copies all of

the switching times from the previous day. So, for example, if you were to press the COPY button on Tuesday

period 1 all of the switching times from Monday would be copied, and then the Heatmiser would move onto

Wednesday.

A screen is displayed to indicate the time have been copied.

To correct any mistakes made, use the DEL Key. If Enter is pressed at any time then

the current settings will be retained.

This is the section used to set the known holiday periods for the year when heating in the zone will not be

required.

Five holiday periods can be set. Follow the steps below for instructions on how to set the holiday periods.

• Press the program key and select option 4.

• You are now prompted to enter the holiday period 1.

You must enter the start date in the DD-MM-YY format. When you

have programmed the start date of the holiday press enter.

• You should now program the length of the holiday. You should calculate the number of days you want

the heating off by counting from the ﬁrst day of your holiday until the last. Now enter the length.

• When the ﬁrst holiday period is set press the enter key.

• Holiday period 2 will now be displayed.

You should program the remaining holiday periods in the same way. When all of the holiday periods have

been programmed the control will revert back to the Data menu.

Important Note:

1. If enter is pressed at any time then the current setting will be retained.

2. To cancel the holiday, put the date to 00.00.00 and length to 00. The holiday will then be cancelled.

Engineers Setup

To enter the engineers section, press the program button and enter the Engineers code. (This will be found

on a label inside the Heatmiser. )

A display like the one shown will now be displayed.

OVER (Override)

This section allows you to enter a limit for the override. Enter two digits

(eg:08 hours) and then press enter to accept the setting.

OPTI (Optimisation)

With the Heatmiser Mistral you are able to set whether optimisation is required (Refer to Terms for further

information).

Should you require optimisation select 1 or 0 to disable it.

Selecting NO will return you to the Setup Menu and turns off optimisation. This means the control will switch

the heating ON at the programmed switching time and will not allow for any warm up period.

This is the amount of time the heating system takes to raise the building

temperature by 1.0°C. An average starting point would be 20 minutes

but because the unit is self learning, it will alter itself by 1minute per day

to adjust to the correct setting.

This is the maximum number of hours before the entered switching time

that the unit could come on to raise the temperature. The maximum

setting is 8 hours but an average setting is 3 hours.

CODE

The code section will work as normal and is used to set the User’s code.

SETUP

This section allows us to conﬁgure the control, set the required fan mode,

enable or disable the internal sensor and set-up the service mode.

CONFIG (Conﬁguring the Heatmiser IQ+)

During the conﬁguration process you will be asked to select the functionality required for the system being

controlled.

• Press PROG

• Enter the Engineer code

• Select 4 for Setup

PURGE OPTION

You are now prompted to select whether a purge is required.

Selecting N here enables you to bypass the next two displays.

Pre-purge activates relay 3 for the amount of time speciﬁed before

the heat relay is activated.

Post-purge will activate relay 3 for the amount of time

Speciﬁed after the heat relay has been switched off.

DOUBLE IGNITION

Enabling this option gives the following functionality.

When the heat relay is activated for the ﬁrst time of each switching time, it will switch off after 30 seconds.

Then after a further 10 seconds the relay is re-energised and will operate as normal.

This operates at the start of every switching period and is used to ensure

that the heater ﬁres when installed in areas where there is a high level

of condensation.

If post purge is enabled, the fan will timeout before the heater re-ﬁres.

PROVING SWITCH

You are now prompted to select whether you have a proving switch

on the system.

When there is a demand for heat, the Heatmiser looks to check ﬁrstly that the proving switch is not made.

Relay 3 is then energised giving pre purge if required. The proving switch then makes followed by relay 2

being energised.

When you have completed the conﬁguration procedure you will be returned to the setup menu screen. At

this point you can press RUN to return to the Normal RUN mode or you can continue to program the other

settings by selecting another menu option.

UP/DOWN TEMPERATURE LIMIT

You are now prompted to enter the limit for the Up/Down temperature

keys. With a limit set to 02, you can increase/decrease the set

temperature by 2°C.
