10.5.4 External heat source (EHS)
This function is used to connect additional heat sources to the heating
circuit, e.g. water-jacketed stove, solar heat.
The heat from the external heat source is diverted into the system when
the set temperature in the external tank is reached, and is at least 5°C
higher than the setpoint in the radiator system. Diversion stops when the
temperature is 3°C higher. The compressor and immersion heater stay idle
for as long as there is sufficient energy in the external heat source. Heat is
diverted to both the heating circuit and to hot water.
This comes to an end when one of the following alarms occur: Primary flow
sensor 1, HP in-sensor, Comm. error HP or if Primary flow sensor 1 is hotter
than 80ºC.
Enter settings under Settings/External heat source.
10.5.5 Ext Boiler
Aim: added heat when the need for heating or hot water is at its highest in
winter, and for hot water when the need for heating is low if this is permitted.
The function allows additional heat sources to be connected to the heating
circuit with lower priorities (costlier heat sources), e.g. district heating or oil
boilers.
Relay for external boiler (E1) is activated by outdoor temperature (or alarm).
When the loss of degree minutes is great enough and the temperature is
high enough (B9), the mixing valve (Y42) opens to the external boiler. Both
the compressor in the heat pump and the immersion heater can be used
at the same time as the external boiler. Heat is diverted to both the heating
circuit and to hot water.
See more installation options in the menu description.
10.5.6 Diff thermostat function
The diff thermostat function is used to transfer heat from a tank with a sensor
(B46) to a tank with a sensor (B47). The function compares the temperatures
in the tanks and, when it is warmer in the first tank (B46), charging starts to
the second tank (B47).
NB: For certain heat sources, e.g. solid fuel boilers, automatic chargers are
recommended, among other things to counteract condensation in the fire
box. However, this function cannot be combined with solar system 2 with
EcoTank. This is because the same circulation pump (G46) is used.
Operation data displays the information “Ext. tank pump/°C”.
10.5.7 Pool (accessory)
A pool can be connected to the system using a diverting valve (Y50). A heat
exchanger should be fitted to separate the liquids. When the pool is heated,
the diverting valve (Y50) changes direction and the pool pump (G51) starts.
The immersion heater is never used to heat the pool. When a constant
flow is desired in the pool water, the pool pump (G51) is connected with
a separate supply and constant voltage. The expansion card accessory is
required to connect pool heating to your heating circuit.
