(space heating) and booster heater (domestic hot water). It is only active if
code 127=1
0. All the electric heaters output can be activated at the same time, if required
1. Maximum 2 electric heaters output can be activated; booster heater has
lowest priority
2. Maximum 1 electric heaters output can be activated; back-up heater output
1 has the highest priority (backup heater output 2 in never ON)
3. Maximum 2 electric heaters output can be activated; booster heater has
lowest priority (backup heater output 2 in never ON)
4. Maximum 1 electric heaters output can be activated; booster heater has the
highest priority (backup heater output 2 in never ON)
The outdoor T° must be below this value to allow the backup heaters to be ON
(unless there is a failure to stop the outdoor unit and acode 1.4=1)
If the difference between water setpoint and water temperature is higher than
this value, backup heaters are allowed to turn on
Time delay (minutes) before switching the backup heaters ON
If in Heat mode, the outdoor temperature is less than the value of this code, the
outdoor unit is turned OFF and the Boiler is used as heat source. Set to
minimum value if this function is not required.
Domestic Hot Water
Defines if Domestic hot water is managed by the system control or by an
external control.
1. Managed by system control
2. Managed by system control with soloar
3. Managed by external control
If domestic hot water tank is not installed set code to 3 and set code 106.0=0
If domestic hot water temperature is equal to or higher than this value,
domestic hot water priority is 0
If domestic hot water temperature is equal to code 134- code 135 - this code,
domestic hot water priority is 0.5
If domestic hot water temperature is equal to or lower to code 134- code 135 -
this code, domestic hot water priority is 1
In heat mode: If room temperature is Room Setpoint - this code, room proirity is
0.5
In cool mode: If room temperature is Room Setpoint - this code, room proirity is
0.5
In heat mode: If room temperature is Room Setpoint - code 137 - this code,
room proirity is 1
In cool mode: If room temperature is Room Setpoint + code 137 + this code,
room proirity is 1
Time delay after which the boiler will be activated if domestic hot water priority
does not decrease due to heat pump operation.
If 0 is selected, boiler does not return on to support the domestic hot water
production.
Define how often (days) the disinfection cycle starts.
If 0 is selected, Disinfection is not performed.
Start time of the Disinfection cycle (hours)
T° to be reached in the Disinfection cycle
Disinfection dwell time (minutes). T° has to be equal to or higher than code 142
for this time period.
If Disinfection cycle is ot completed within this time (hours), the antilegionalla
cycle is considered failed.
