E.6. AUXILIARY HEAT SOURCE (EL. HEATING ELEMENT)
OPTIONAL ACCESSORY (NOT REQUIRED)
For Variant 1 (options A, B, C) only
Menu for an aux. heat source (el. heating element) is available when the system
configuration “
1 (Combi+HC+SF)
” is selected. The auxiliary heat source is switched
on when there is a demand to heat up the thermal store (a request from a heating
circuit).
Switching of the el. heating element is controlled by a time program (5.8.9.) or by a
request from the heating circuit thermostat (5.8.2.). If the thermostat is switched off,
the auxiliary heat source will never be switched on!
5.8.2. Heating circuit thermostat
The aux. heat source will be activated only if there is a request for thermal store
heating for a heating circuit.
5.8.3. Temperature to switch on an aux. heat source (TH Set)
The aux. heat source will switch on when the temperature at the reference sensor,
depending on the active request, drops below this value (in case of an active request,
the reference sensor is the DHW sensor – see 5.3.8., in case of an active request for
thermal store charging, the reference sensor is the thermal store sensor – see 5.1.16.).
5.8.4. Switch-on delay
The aux. heat source switch-on delay.
5.8.6. Ecomode
This mode permits either blocking (
Shutdown
mode) or lowering the switch-on
temperature of the aux. heat source from TH Set to Teco temperature (
Decrease
mode) in case when the boiler is active.
5.8.7. Reduced switch-on temperature to start an aux. heat source (Teco)
The temperature for switching on an auxiliary heat source when the option
Decrease
is selected (in the Energy Saving Mode 5.8.6).
5.8.8. Heating circuit compensation
The heating water temperature reduction when the option
Decrease
is selected (in the
Energy Saving Mode 5.8.6.) and the aux. heat source was switched on.
5.8.9. Heating element periods
This is intended to block the heating element outside of the preset time program.
