10.9 ACTIVATION OF INTEGRATION HEATERS AND BOILER IN JOINT OPERATION AND IN
SUBSTITUTION OF HEAT PUMP COMPRESSOR
The auxiliary parts that can be used for joint operation or for operation in substitution are:
•
boiler
• plant integration heater
• DHW integration heater
Considering the operating modes in heating and/or DHW, there are 4 operating areas:
r22
Heat pump + Boiler/Heater
JOINT OPERATION I ZONE
Heat pump/Heater
JOINT OPERATION II ZONE
Boiler/Heater
OPERATION IN SUBSTITUTION
Heat pump
STANDARD WORKING
r28
r08
Outside
temp.
If you need to change the values of the parameters r22, r28, r08 , follow r22 ≥ r28 ≥ r08 .
Setting r22=r28 allows you to eliminate the zone relative to joint operation bracket I; setting r28=r08 allows you to eliminate the zone relative to
joint operation bracket II; setting r22=r28=r08 allows you to eliminate both brackets relative to joint operation.
Do not modify value r08, as it could jeopardise operation of the unit
10.9.1 OPERATION IN HEAT PUMP MODE
Normale operation of the heat pump in which the integration heaters and-or the boiler only intervene when a heat pump alarm is triggered.
10.9.2 JOINT OPERATION (I BRACKET)
If the outdoor temperature is between r22 and r28 , the compressor operates in synergy with the auxiliary heaters in winter or DHW mode.
In this operating bracket, first the heat pump is activated and after r12 minutes the plant side auxiliary heaters, or after r16 minutes the sanitary
side auxiliary heaters.
The intervention priorities are defined by the parameters r14 , r20 , r23 , r24 .
It goes back to normal operation if the outdoor temperature is greater than r22 +1.0 (°C).
NOTE : In the joint operating bracket, the boiler is temperature controlled by the plant water remote probe (if enabled). In particular, if the
temperature detected by the remote probe is lower than the Hea setpoint, the boiler is switched on and then will go off when the temperature
detected by the remote probe is higher than the Hea setpoint. The heat pump follows the activation logic described in paragraph 10.5.
If the remote plant water probe is not enabled, the boiler will be managed by the delivery probe of the heat pump.
10.9.3 JOINT OPERATION (II BRACKET)
If the outdoor temperature is between
r28
and
r08
, the compressor operates in synergy with the auxiliary heaters.
In this operating bracket, first the boiler is activated, then the heat pump and auxiliary heaters intervene after a time defined by r12 (minutes)
for the plant side and
r16
(minutes) for the sanitary side
The intervention priorities are defined by the parameters r14 , r20 , r23 , r24 .
It goes back to normal operation if the temperature rises above
r28
+1.0 (°C).
Note : In the joint operating bracket, the boiler is temperature controlled by the plant water remote probe (if enabled). In particular, if the
temperature detected by the remote probe is lower than the
Hea
setpoint, the boiler is switched on and then will go off when the temperature
detected by the remote probe is higher than the Hea setpoint. The heat pump follows the activation logic described in paragraph 10.5.
If the remote plant water probe is not enabled, the boiler will be managed by the delivery probe of the heat pump.
