2.5.6 Other Thermal

At the Commissioning parameter setting page, by touching "Other thermal", the control panel will access to the corresponding setting page.
At the "Other thermal" setting page, "Other thermal" can be set to "With" or "Without"; "T-Other switch on" the external temperature value must
be set below which the generator can activate (3 ° C differential).
When "Other thermal" is set to "With", it is allowed to set the operating mode ("Logic") for the backup thermal source.
NOTE

There are three working logics for it:
Logic 1
In "Heat" mode and "Heat + hot water" mode, the set point of other thermal should be equal to that of "WOT-Heat"; in "Hot
water" mode, the set point should be the smaller one between "T-Water tank" +5°C and 60°C.
The water pump for other thermal must be always active under the "Heat" mode.
Under the "Heat" mode, the 2-way valve will be controlled based on the setting of the control panel. During heating operation, the
water pump of the heat pump unit will be stopped; however, during standby status, the water pump will start but the other thermal will
stop.
Under the "Hot water" mode, the 3-way valve will switch to the water tank, the water pump of the heat pump will always stop but the
other thermal will start.
Under the "Heat + Hot water" mode, the other thermal only works for space heating, and the electric heater of the water tank works
for ACS water heating. In this case, the 2-way valve is controlled according to the control panel settings and the 3-way valve is locked
on the system side. During heating operation, the water pump of the heat pump unit will be stopped; however, during standby status,
the water pump will start.
Logic 2
In "Heat" mode and "Heat + hot water" mode, the set point of other thermal should be equal to that of "WOT-Heat" and both are or
lower than 60°C; in "Hot water" mode, the set point should be the smaller one between "T-Water tank" +5°C and 60°C.
The water pump for other thermal must be always active under the "Heat" mode.
Under the "Heat" mode, the 2-way valve will be controlled based on the setting of the control panel. During heating operation, the
water pump of the heat pump unit will be stopped; however, during standby status, the water pump will start but the other thermal will
stop.
Under the "Hot water" mode, the 3-way valve will switch to the water tank, the water pump of the heat pump will always stop but the
other thermal will start.
Under the "Heat + Hot water" mode ("Heat" takes the priority), the other thermal only works for space heating and the electric heater
of the water tank works for water heating. In this case, the 2-way valve is controlled according to the control panel settings and the 3-
way valve is locked on the system side. During heating operation, the water pump of the heat pump unit will be stopped; however,
during standby status, the water pump will start.
Under the "Heat + Hot water" mode ("Hot water" takes the priority), the other thermal works for space heating and water heating. The
other thermal will work for water heating firstly, after reached "T-water tank", other thermal turns to space heating.
Logic 3
The heat pump will only send a signal to other thermal, but all the logic of control must be "stand alone".

It is necessary connect the water probe RT5, otherwise an alarm appears.

" WOT-Heat " and "Electric Resistance" cannot be activated simultaneously.

The setting is memorized and re-proposed in case of power failure (see 2.6.1 On/Off memory).

The default value is Without.
