Default

Heating and DHW
Pack 3
Heating only
(Range -15C to 15C)
0C
The lower external air temperature on the weather compensation
graph. Typically this is the „design temperature‟ which is determined
during the design process and is normally between -1C to -5C.
(Range -15C to 15C)
15C
The higher external air temperature on the weather compensation
graph. Recommended setting of 15C or the building base
temperature if known.
(Range 25C to 55C)
55C
The water flow temperature corresponding to the lower external air
temperature on the weather compensation graph. The is determined
based upon the choice of heat emitters by the system designer.
Typical values are:
Under floor: 35C
SmartRads: 45C
Radiators: 55C
(Range 25C to 55C)
32C
The flow temperature required for the heat emitters to give the
correct heat output at the minimum design temperature. Typical
values are:
Under floor: 20C
SmartRads: 35C
Radiators: 35C
(Range 5C to 35C)
18C
The external air temperature above which heating is no longer
required so the heat pump operation is blocked. Typical value of
18C.
(Range -15C to 20C)
-3C
The external air temperature below which the inline flow boiler will be
allowed to operate during normal operation. This is dependent upon
the „bivalent temperature‟ as determined during the design process.
Typical values between -1C and -5C.
(Range -40C to 75C)
55C
The temperature of the stored hot water within the domestic hot
water cylinder. Note that if the temperature is higher than the heat
pump can achieve on its own via the compressor the immersion will
automatically heat the cylinder to the required temperature.
45C

The advanced settings can only be set if the
Operation LED is OFF.
