Heat pump type
Select which heat pump model is in use: T8-T80,
V7.0-V30.0, Vs6.0-Vs12.0, V8-15, T8-T60, S8-S15,
Geopro GS or Geopro SH.
Function
Select whether the pump is full effect or limited (partial)
effect. Geopro pump models are always partial effect.

The maximum limit varies from 53° C to 55° C:
- When the outdoor temperature is above +15°C,
the maximum limit is 53° C.
- When the outdoor temperature is below -5° C,
the maximum limit is 55 ° C.
- When the outdoor temperature is from +15° C to -5°C the
temp. limit changes linearly from 53° C to 55° C.
Status
You can check what asks for or prevents the compressor and / or electric heater from turning
on. Start and stop delays are also displayed. In addition, the running time / on of the compres-
sor and the electric heater is displayed.
Function and its terms
A compressor running command is given, when
•
the temperature of the accumulator’s upper part
(meas.10)
drops below the [“Accumulator Upper part MIN” - (“Accumulator Upper
part hysteresis“/2)]
or
•
the temperature of the accumulator’s lower part (
meas. 11
) drops below [controller indicated H1 supply water tempe 5°C -
“Accumulator Lower part hysteresis”]
or
•
the temperature of the accumulator’s lower part (
meas. 11
) drops below the “Accumulator Lower part MIN “ setting.
The compressor stops running, when
•
the temperat. of the accumulator’s upper part (
meas. 10
) rises above the [“Accumulator Upper part MIN” + (“Accumulator Upper
part hysteresis“/2)]
and
•
the temp. of the accumulator’s lower part (
meas. 11
) rises above the [controller indicated H1 supply water tempe 5° C]
and
•
the temperature of the controller’s lower part (
meas. 11
) rises above the [“ Accumulator Lower part MIN” + “Accumulator Lower
part hysteresis“] temperature.
Compressor running is inhibited,
•
if a 3-phase compressor is used and less than 5 minutes have elapsed since the previous run
•
if a 1-phase compressor is used and less than 10 minutes have elapsed since the previous run
•
if the hot gas temperature measurement (
meas. 12
) is connected and the temperature of the hot gas rises above 125°C
•
(the compressor starts running when the temperature drops to 122° C).
•
if the temp. of the accumulator’s upper part (
meas. 10
) exceeds 95° C (the compressor starts running when the temperature
•
has dropped to 85° C)
•
if the temperature of the accumulator’s lower part (
meas. 11
) exceeds the calculated “Lower part maximum limit” (53...55°C).
•
The compressor starts up when the temperature of the accumulator’s lower part has dropped 3° C below the calculated “Lower
part maximum limit”
•
if the electrical heating resistor has been switched on
The electrical heating resistor switches on when condition 1 and condition 2 is met
Condition 1
•
Compressor control has been on for 12 hour (adjustable) and the temp.. of the accumulator’s lower part has not risen a 0.5°C
or
•
the compressor alarm is active and an attempt has been made to restart the 1-phase compressor after a delay time of 10 minutes
/ the 3-phase compressor after a delay time of 7 minutes
and
and after this an attempt has been made to start the compressor
for every 60 min.
Condition 2
•
The temperature of the compressor’s upper part
(meas. 10)
is below [“Accumulator Upper part MIN” - (“Accumulator Upper part
hysteresis“/2) - “Upper part hysteresis El. heating ”]
or
•
the temp. of the accumulator’s upper part
(meas. 10)
is below the [controller indicated H1 supply water temperature -
”Upper part hysteresis El. heating ”]
•
(This calculation takes into account that the temp. of the controller indicated H1 supply water temp. is a maximum of 50° C.)
The electrical heating resistor switches off, when
• the temperature of the accumulator’s upper part (
meas. 10
) rises above the [Accumulator Upper part MIN” - (“Accumulator
Upper part hysteresis“/2)]
and
• the temperature of the controller’s upper part is above the [controller indicated H1 supply water temperature]
Control of the electrical heating resistor always ends
•
if the temperature of measurement 10 rises above 95° C; the temp. must drop to 85° C before the electrical heating elementcan start up
