UNDER 5°C DEFR Safety defrosting occurs when the outdoor temperature has been below 5° for a
setnumberofdays,shunts+20°Cfor10minutes.
7D

MIN TIME DEFROST Minimum time between two defrosts in minutes. 45M
(interval: 10M / 60M)
DEFR SENSOR Shows the actual temperature of the incoming air to the outdoor unit. -
Sub menu SERVICE -> OPTI (Opti models)
The menu applies to Optimum models with speed controlled circulation pumps and only appears if ON in SERVICE -> INSTALLATION ->
SYSTEM -> ADDITION -> CONTROLLED CP menu is selected. Used to change the circulations pumps’ operating settings.

TEMP DIFF CIRC. Desired temperature difference between supply and return line for the heating
system..
8°C
(interval: , 0°C / 15°C)
TEMP DIFF BRINE Desired temperature difference between supply and return line for the brine
system.
3°C
(interval: , 0°C / 15°C)
START FLOW CIRC. Speed control of the heating system’s circulation pump in Volts. Higher voltage
gives a greater circulation pump speed, which gives a lower temperature differ-
ence. A low voltage gives a greater difference.
3 - 10 = Manually adjustable speed, where 3 is low voltage and 10 is high volt-
age.
7V (interval: 3V / 10V)
START FLOW BRINE Speed control of the brine system’s circulation pump in Volts. Higher voltage
gives a greater brine pump speed, which gives a lower temperature difference. A
low voltage gives a greater difference.
3 - 10 = Manually adjustable speed, where 3 is low voltage and 10 is high volt-
age.
10V (interval: 3V / 10V)
CONST. FL. CIRC. If TEMP DIFF CIRC is set to XX the flow is continuous with this value in the heat-
ing system. Value indicated in Volts.
7V (interval: 3V / 10V)
CONST. FL. BRINE If TEMP DIFF BRINE is set to XX the flow is continuous with this value in the brine
system. Value indicated in Volts.
10V (interval: 3V / 10V)
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 (interval: 3V / 10V)-
MAX H.W CHARGE Highest supply temperature during water heating. 55°C
(interval: 50°C / 65°C)
MIN H.W CHARGE Lowest desired supply temperature during water heating. 50°C
(interval: 30°C / 65°C)
Sub menu SERVICE ->HGW (DHP-H Opti Pro)
The menu applies to the DHP-H Opti Pro model with de-superheater and only appears if ON in SERVICE -> INSTALLATION -> SYSTEM ->
ADDITION -> HGW SHUNT menu is selected. Used to change the de-superheater’s operating settings.

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
(interval: 15K / 35K)
HOT WATER DIFF. Shows actual difference between the HGW sensor and water heater’s start sen-
sor.
-
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
