MIN FLOW CIRC.
Lowest permitted voltage (speed) of the circulation pump’s flow in the heating system. If
there is no heat demand, there may still be a demand to read in the temperatures for the
sensors in the system and the circulation pump therefore must be run.
3V(range: 3V / 10V)
MAX H.W
CHARGE HW
Highest supply temperature during water heating. 55°C(range: 45°C /
65°C)
MIN CHARGE.
HW
Lowest desired supply temperature during water heating. 50°C(range: 30°C /
65°C)
MIN TEMP BRINE Lowest allowed temperature for the cold carrier.
8°C(range: 6°C /
20°C)
9.8 Sub-menu HGW
The menu applies to the heat pumps with de-superheater and only appears if ON in SERVICE -> INSTALLATION -> SYSTEM -> ADDITION -
> HGW menu is selected.

HGW TEMP.
Shows the HGW sensor after the de-superheater (the supply temperature to water heater) in °C. -
TEMP DIFF Desired difference between the HGW sensor and water heater’s start sensor. 20K(range: 15K /
35K)
HOT WATER
DIFF.
Shows actual difference between the HGW sensor and water heater’s start sensor. -
HOT WATER
TO RAD.
If there is a heat demand, the HGW shunt switches to the heating system when the weighted
value is greater than the total of the START temperature for hot water and this value. Example:
40°+3K = at a temperature of 43°C in the water heater, the shunt switches to the heating system.
3K(range: 1K /
10K)
MAX TEMP. Max temperature of the water in the water heater. The temperature is measured on the peak
sensor in the water heater.
N
Domestic hot water can have this temperature, which can mean that
an external mixer valve may be required.
95°C(range: 60°C /
100°C)
START HGW
The number of seconds the HGW shunt is to open at HGW start is the starting point of shunt
opening. The opening time for the HGW shunt from fully closed to fully open towards the water
heater is 30 seconds.
7S(range: 0S /
30S)
INITIALIZING
HGW
The time in seconds before control of HGW shunt starts after HGW start. 60S(range: 10S /
90S)
INTEGRAL DE-
LAY
Delay of integral calculation in seconds after the integral value for HGW has been reached. 10S(range: 5S /
120S)
HGW-SHUNT
TIME
The time that the signal is active to open or close the HGW shunt completely. 35S(range: 15S /
60S)
HGW INT.
BOUND.
Integral value (parameter) for HGW. 60(range: 10 /
120)
HGW INTE-
GRAL
Shows the actual value for the HGW integral. Plus indicates that the shunt opens towards the
water heater and minus indicates that the shunt opens towards the heating system.
-
PULSE WIDTH How long the plus or minus signal to the shunt is to be high when the HGW integral has been
reached.
0.25S(range:
0.20S / 1.00S)
