OPERATION IN SUBSTITUTION
If the outdoor temperature drops below
r08
use of the heat pump compressor will be inhibited.
- If the auxiliary system is composed of plant and/or DHW heaters, they are active in substitution of the compressor with defined times,
r12
(minutes) for plant side and
r16
(minutes) for sanitary side.
Whereas in the operation in substitution bracket, the integrations do not need to be enabled with
r10
or
r15
as the heaters need to operate in
substitution (and not in integration) of the heat pump (therefore simply select the type of use with the parameter
r24
).
- If the auxiliary system is a boiler with autonomous circulator (
r32
=
1
or
3
).
The circulator of the heat pump is off, after
P01
(default 30 seconds) the boiler is enabled.
NOTE
: With water side antifreeze protection, the pump used is activated (or remains active) anyhow.
- If the auxiliary system in substitution is a boiler with autonomous temperature control (
r32
=
0
or
2
).
The boiler is enabled regardless of the temperature control of the heat pump.
- If the auxiliary system in substitution is a boiler without circulator (
r32
=
0
or
2
).
The circulator of the heat pump is on when the boiler is enabled.
The compressor switches back on if the temperature rises above
r08
+
r09
(°C) (r09=1.0 °C by default).
10.10 OPERATING BRACKETS - ACTIVATION OF INTEGRATION HEATERS (PLANT REMOTE
WATER PROBE NOT ENABLED)
The possible configurations of the integration parameters are listed in tables 1,2,3 and 4 shown below, divided by operating brackets (the op
-
erating modes and possible values of the parameters are indicated in the “STATUS” boxes and in the parameters “
rxx
” so that a given order
of intervention of the integrations occurs in a certain operating mode of the unit; other statuses and values of the parameters can be selected
instead and therefore they are provided in the same cell separated by the symbol ”/”).
