1.5.13 Electric heater
In case of a problem on the electric heater (safety thermostats), the electric heater is shut off and the fault is signalled.
Electric heater load shedding or a choice of heating coil is available.
The aim is to use the same input ID1 to control either:
- Electric heater load shedding (function also available via communication with the CMS)
- The choice of heating coil which can be used (electric or hot water, only for coil 1) (function also available via communication
with the CMS)
The configuration of this input ID1 will be accessible from level 3 (Manufacturer) only.
These 2 control principles do not cause an alarm to be created.
