10.4
COOLING
Parameter
Meaning
COOLING
Activates the cooling function.
Factory setting:
, range:
, ACTIVE COOLING, INTEGRATED IN HP
COOLING TIME
When the heat pump must alternate between different demands for example heating, hot
water, pool heating and cooling, cooling will be produced longest according to the set
number of minutes.
Factory setting: 20M, range: 5M – 40M
MAX START TEMP
Highest settable temperature for START parameter in INFORMATION -> COOLING.
Factory setting: 30°C, range: COOLING->START – 55°C
MIN STOP TEMP
Lowest settable temperature for STOP parameter in INFORMATION -> COOLING.
Factory setting: 16°C, range: 5°C – COOLING->STOP
ROOM SENSOR
Activation of room sensor function for influencing cooling production.
Factory setting:
, range:
– ON
COOL.HYST.RS LOW
Compressor is stopped if the temperature from the room sensors falls below the desired
temperature minus COOL.HYST.RS LOW
COOL.HYST.RS HIGH
Compressor is not permitted to start if the criteria are not met.
10.5
AUX. HEATER
Parameter
Meaning
MAX STEP
Maximum number of permitted steps for auxiliary heating.
= no auxiliary heating per-
mitted (Means that only AUTO, HEAT PUMP or [SYMBOL] can be selected and that no anti-
legionella operation is possible.) P = the potential free output controls an immersion heater
connected before the hot water reversing valve and not an external auxiliary heater as nor-
mal.
Factory setting:
, range:
, – 5, P
INTEGRAL A2
Two conditions must be fulfilled in order to start the auxiliary heater: the integral’s value to
start must be less than integral A2, and the supply temperature must be 2°C lower than the
calculated temperature. See INTEGRAL, Page 43 for more information.
Factory setting: -600°min, range: -990°min – A1 - 10°min
HYSTERESIS
If the difference between the actual supply temperature and the calculated supply temper-
ature is too great (see Important parameters), either the integral value is set to start value
A2 (starts the auxiliary heater) or to 0 (stops the auxiliary heater ).
Factory setting: 20°C, range: 5°C – 30°C
MAX CURRENT
Refers to main fuse in the unit, in amperes. An expansion card must be connected for cur-
rent measurement.
Factory setting: 20A, range: 16A – 35A
HOT WATER STOP
Stop temperature for hot water during AUX. HEATER. The value is read off by the hot water
sensor.
Factory setting: 60°C, range: 50°C – 65°C
