All the terminals referred to in the following explanations are to be found on the terminal board located inside the elec-
trical panel and called “installer terminal block” or “electronic controller A1 terminals” (see wiring diagram).
FIXED SET POINT OPERATION CONTACT (SA6)
Contact SA6 allows operation of the heat pump with a fixed
outlet set point defined by parameter 5952 (default = 50°C).
Closing the contact disables the outside temperature probe
and the room unit, the outlet temperature depends exclu-
sively on the set point set for parameter 5952.
ROOM UNIT (A3)
Installation instructions
The room unit must be located in a reference room to con-
trol the room temperature, keeping in the following factors
consideration:
INSTALLER CONNECTIONS
I A
REMOTE ALARM (RD1)
For remote display of unit shut-down due to an operating
fault, an audible or visual alarm warning device can be con-
nected between terminals 6 and 7.
Connect the phase to terminal 7 and the alarm signal device
between terminal 6 and the neutral N.
ELECTRIC HEATER CONTACT (SA1)
To use an electric heater as an auxiliary heating element for
the production of domestic hot water.
Follow the instructions shown on the instruction sheet
enclosed with the electric heater kit if supplied by Cli-
maveneta, otherwise see the wiring diagram in this manual.
For further details see the chapter “Control”.
BOILER CONTACT (SA2)
To use a boiler as an auxiliary heating element or to replace
the heat pump, connect the phase to terminal 11 and the
control device, auxiliary relay, between terminal 10 and the
neutral N.
For further details see the chapter “Control”.
DEACTIVATION CONTACT FOR EXCESS POWER CON-
SUMPTION (SA3)
The heat pump accepts a external deactivation signal from
contact SA3, if using a system for managing power con-
sumption that disconnects active devices based on set prior-
ity, so as to avoid the overload switch on the power meter
from being triggered.
Connect the external contact to terminals 16 and 17.
Contact SA3 closed, heat pump operation disabled.
Contact SA3 open, heat pump operation enabled.
REDUCED ELECTRICITY RATE CONTACT (SA4)
The heat pump accepts an external signal from contact SA4
to activate the forced refilling of the reserve storage tanks
based on different electricity rates during the day.
During reduced rate periods, the heat pump can be forced
on so as to heat the domestic hot water or system storage
tank, where fitted.
Connect the external contact to terminals 18 and 19.
Contact SA4 closed, heat pump operation enabled (forced
operation during the reduced rate period).
Contact SA3 open, heat pump operation disabled.
CONTACT (SA5)
Not used
COMPRESSOR ON SIGNAL (GN1)
For remote display of the compressor operating status, an
audible or visual alarm warning device can be connected
between terminals 12 and 13.
Connect the phase to terminal 13 and the signal device
between terminal 12 and the neutral.
CONNECTING A FLOW SWITCH (F3)
If a flow switch is used, connect it to terminals 14 and 15 on
the installer terminal board, after having removed the
jumper.
DOMESTIC HOT WATER 3-WAY VALVE (YV3)
To configure a 3-way for the production of domestic hot
water (supplied by Climaveneta), make the following con-
nections as shown on the instruction sheet enclosed with
the accessory.
The 3-way valve for the domestic hot water production, if not
supplied by Climaveneta, should have the following charac-
teristics:
- Voltage 230V AC, 50/60 Hz
- Opening and closing time 10s.
- P delta 500 kPa
- Fluid temperature 0°C to 90°C
Use three-way valves with a pressure drop below 20 kPa.
For further details, see the chapter on “Operating character-
istics”.
