11.5.5 External 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.
11.5.6 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/Diff thermostat function" displays the information "Status
(On/Off).
11.5.7 Pool (accessory)
A pool can be connected to the system using a 3-way valve (Y50). A heat
exchanger should be fitted to separate the liquids. When the pool is heated,
the 3-way valve (Y50) changes direction and the pool pump (G51) starts.
The electric 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 Extension Card accessory is required to
connect pool heating to your heating circuit.
11.5.8 Solar heat (accessory)
Solar heat is connected to the system through an external heat source tank
(EHS-tank).
The number of solar panels which can be connected depends on the volume
of water in the product/tanks to which the solar panels are to be connected.
System 1
System 1 is a system structure with solar heat going directly to an external
heat source tank (EHS-tank).
Charging conditions (main conditions, factory settings)
• Charging starts when B31 is 7ºC warmer than B6.
• Charging stops when there is a difference of 3°C between B31/B30 or
when the charge temperature is reached.
The tank for the external heat source (01) can also have a solar coil, in which
case the heat exchanger (F2), pump (G32) and non-return valve (Y11) are not
required.
