Safety Instructions

2.1

Application

The Smile controller family SDC / DHC 43 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 degrees 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 controll 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 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.
2.3

Do not separate the controller from the mains

If this happens the back-up battery will be unnecessarily stressed. Also the frost
protection functions of the controller will be out of order.
