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.
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.
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.
