Meaning
The installation is off. Any active alarms reset.
Automatic operation with both heat pump and auxiliary heater permitted. If the
number of power stages for auxiliary heating are set to zero (SERVICE -> AUX.
HEAT -> MAX STAGE) only AUTO or OFF can be selected as operating mode.
Operation with only heat pump permitted. NOTE! No peak heating charging
(legionella function) with only heat pump operation.
Operation with only auxiliary heater permitted.
Operation with heat pump for hot water production and auxiliary heater during
peak heating charging (legionella function).
Only appears when MANUAL TEST in the SERVICE menu is active. Outputs con-
trolled manually.
Meaning
Calculated supply temperature at 0°C outdoor temperature. Shown as a graph
that also shows MIN and MAX values.
Minimum permitted supply temperature, if the temperature for heat stop has
been reached and the heat pump has stopped.
Maximum permitted supply temperature.
Local increase or reduction of CURVE at an outdoor temperature of +5°C. Shown
in the graph for CURVE.
Local increase or reduction of CURVE at an outdoor temperature of 0°C. Shown
in the graph for CURVE.
Local increase or reduction of CURVE at an outdoor temperature of -5°C. Shown
in the graph for CURVE.
Maximum outdoor temperature when heat production is permitted.
If HEAT STOP applies, the outdoor temperature must drop 3°C below the setting
before HEAT STOP stops.
Only appears if the tariff control function has been activated. Lowering set room
temperature. Active at 10 kohm connection at EVU input.
Only displayed if a room temperature sensor is installed. Determines how much
the control computer is to refer to the room temperature sensor when calculat-
ing the supply temperature.
Only appears if POOL is selected. The temperature in the pool is controlled by a
separate sensor regardless of the heating and hot water system.
Only appears if POOL is selected. If the difference between the actual supply
temperature to pool and the calculated supply temperature is too great, either
the integral value is set to start value A1 (the heat pump starts) or the value is
set to 0 (stops the heat pump).
Meaning
Calculated shunt group temperature at 0°C outdoor temperature. Shown as a
graph that also shows MIN and MAX values.
Minimum permitted shunt group temperature, if the temperature for heat stop
has not been reached.
Maximum permitted shunt group temperature.
