INSTRUCTION MANUAL – HEAT PUMP
It is also necessary to set a positive limit temperature
for which the heat pump will be turned on. The pos-
sibility of starting the heat pump is controlled by a
relay with a hysteresis of 1°C. For example, selecting a
limit temperature of 12°C, after reading 11.5°C from the
outside temperature sensor, the heat pump will turn
off, while start-up will be possible when the tempera-
ture drops below 12.5°C. In order for the algorithm
to work, the switching conditions must be met for a
certain period of time.
The next window selects how many heating circuits
the user has. Depending on your choice, the appro-
priate windows will be displayed later.
The next step is to configure the CH buffer pump (if any). This is the circulating pump after the buffer that unloads
the buffer. You can set this pump to be off all the time, on all the time, on only when the heat pump is on, or make
adjustments based on the temperature in the buffer. Then set the temperature you want the buffer to reach, as
well as the hysteresis. If the temperature of the water in the buffer exceeds the set point, then the pump will
start and unload the buffer. The process will continue until the temperature drops below the setpoint - hysteresis
value.
If two heating circuits have been selected, then in the
next window the fixed working value of the second
heating circuit pump expressed in percentage is set.
