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

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
This code displays the
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 1 2 1
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 UI 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)
