DESCRIPTION
This code displays the nominal heat pump capacity
[kW].
This code displays the Entering Water Temperature read
by the EWT sensor.
This code displays the Leaving Water Temperature read
by the LWT sensor.
This code displays the refrigerant temperature value
read by the TR sensor.
This code displays the operating mode requested by the
System Control:
0. Off
1. Stand by
2. Cooling
3. Heating
4. N.A.
5. N.A.
6. Rating Heating
7. Rating Cooling
8. Freeze Protection
9. Defrost
10. High Temperature Protection
11. Time guard
12. System Fail
This code displays the list of the all fault codes detected
by the outdoor unit. If no fault are occurring, no codes
will be displayed.
This code displays the GMC Software Version
This code displays the GMC Software Release
This code displays the working on hours (x10) of the
water pump.
This code displays the current water set-point defined
by the system control.
This code is use to set the different OFF logics:
1. Standard OFF
2. Controlled Off Cycle (only if HP is controlled by dry
contact)
This code is use to select the output connected at PIN 5
on terminal strip:
1. Alarm signal
2. Signal of reached air temperature set-point
This code is use to set the OAT threshold value under
which only the external heat source will be operative as
per algorithm. (Stop HP)
This code is use to set which temperature the NUI shall
display in temperature zone.
1. Indoor air temperature
2. Leaving water temperature (from LWT sensor)
3. Entering water temperature (from EWT sensor)
4. Refrigerant temperature (from TR sensor)
5. Suction temperature (from TS sensor)
6. Discharge temperature (from TD sensor)
7. Refrigerant temperature (from TE sensor)
This code is use to set the OAT threshold value under
which both the heat pump and the external heat source
will be operative as per algorithm.
This code is use to set the delay time after which, when
(temperature set in code 148) < OAT < (temperature set
in code 150), the external heat source will switch on .
The counting of the time starts when the activation of
the EHS is required as per algorithm (if current water
temperature) < (water temperature set-point – auxiliary
hysteresis)
