DESCRIPTION
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)
This code is use to set the hysteresis temperature needed to activate the
external heat source.
logic can be activated:
1. Yes, SHW logic is always actives. If OAT < Par148, Heat Pump will turn ON to
produce SHW.
2. No, SHW logic can be activated only in Heat or Cool mode. No SHW
production when OAT < Par148.
and OAT < temperature value set in Code 148:
0. Always On

(temperature value set in Code 148):
2. Always On
This code is use to select the output connected at PIN 12 on terminal strip. In case
an additional water pump option is active, this code is use to select its operating
logic vs the SHW request (if OAT > (temperature value set in Code 148).
0. Trace heater installed for the anti frost logic 0 2 1
means that in case of SHW activation, the additional WP will be ON.
always OFF when SHW is activated.
