SDC / DHC 43 Safety Instructions

EN2H-0220 GE51 R1005 4

2 Safety Instructions

2.1 Application

The Smile controller family DHC/SDC is designed

exclusively for the control of warm water heating and

district heating systems including domestic hot water

control. These systems should not exceed a flow

temperature of 120 °C.

2.2 Conditions for start-up

CAUTION The heating installation must be completed and filled with

water in order to prevent the pumps from running dry and

to avoid damage for the boiler.

The control system must be installed according to the

mounting instructions.

All electrical connections (power supply, burner, valve

actuator, pumps and sensors) must be carried out

according to the local rules and standards and must

comply with the attached wiring diagrams.

If a floor heating system is connected, a limiting

thermostat must switch off the pump if the flow

temperatures are too high.

The heating specialist must check the complete

installation before switching on the controller.

IMPORTANT NOTE! The actual time and date are already adjusted from the

factory and backed up by a battery.

There is a basic time program already activated and the

control functions for standard heating systems with low

temperature boilers are pre-adjusted.

EN2H-0220 GE51 R1005

2.3 Do not separate the controller from the mains

If this happens, the back-up battery will be unnecessarily

stressed. In addition, the frost protection functions of the

controller will be out of order.

2.4 Electric installation

Qualified personnel must carry out all electrical

connections.

2.5 Cable dimensions

1.5 mm² for all 230 V cable (power supply, burner,

pumps, actuators).

0.5 mm² for sensors, selectors, bus and analogue in- and

outputs.

2.6 Maximum cable length

Sensors selectors and analogue inputs

A maximum cable length of 200 meters is recommended.

Longer distances are possible but increase the risk of

interferences.

Relay outputs

Unlimited cable length.

Bus connections

A maximum cable length of 100 meters is strongly

recommended.

2.7 Cable installation

Cables for 230 V must be installed separate from low

voltage (sensor selector bus) cables.

2.8 Cabinet earth and ground

Please install and connect the controllers according to

local rules and standards!

2.9 Domestic hot water higher than 60 °C

WARNING Please note that in the following cases there is a danger

at hot water tabs (kitchen, bath). In order to avoid

scalding please mix enough cold water.

Anti legionella automatic

If the anti legionella automatic is activated, the domestic

hot water will automatically be heated up to temperatures

around 65 °C order to kill legionella bacteria in the hot

water system.

Manual operation / Emission measurement

In the manual mode / emission measurement mode the

domestic hot water can be heated up to the maximum

possible boiler temperature because the burner and all

pumps are switched on and the valves will be completely

opened. In addition, here there is the danger of scalding

at all warm water tabs in the building. Please mix enough

cold water or switch the domestic hot water loading

pump manually off (if there is a switch at the pump).

Heating and domestic hot water are not temperature

controlled in these modes. These modes are especially

used by the emission measurement specialist or by the

installer in case the controller is defect. The high water

temperatures can however be avoided if the boiler

thermostat is adjusted to a max. of 60 °C.

2.10 Connecting accessories

CAUTION According to VDE 0730 the power supply for the

controller must have a separate main switch for life and

neutral. Please follow local rules and standards for

cabinet earth and ground!

As soon as there is power supply at the terminals 21, 22,

2, 6, 12 and 18, also the terminal rows X3 and X4 will

carry 230 V connections!
