OPERATING AND COMMISSIONING INSTRUCTIONS
IV.12. Hot water coil integrated (PREMIUM BC) – changeover water coil (PREMIUM CO) or
external cold or changeover coil
Pay attention to let the doors free of access (ducts, cables)
Hot water coil is mounted in the unit (PREMIUM BC and PREMIUM CO version), defrost Thermostat is connected. You
have to cable the 3 ways valve. If a cold battery is used or changeover battery in duct is used, move the supply sensor after the
battery.

3 WAYS VALVE MUST BE CONNECTED WHEN POWER IS OFF
Connect the servomotor of the 3 ways valve as following instructions:
Hot Battery :
Terminal 15 on +24V (G) of the 3 ways valve actuator
Terminal 16 on 0V (G0) of the 3 ways valve actuator
Terminal 17 on 10V (Y) of the 3 ways valve actuator
Connect NC contact (C et 2) of the THA (Deicing Thermostat) on 5 and 6.
Possibility to connect the circulator on the DO3 terminal of the regulator and the terminal block 18.
(Note: 24V output to relay)
Cold Battery : Install siphon on the drain evacuation
Terminal 28 on +24V (G) of the 3 ways valve actuator
Terminal 29 on 0V (G0) of the 3 ways valve actuator
Terminal 30 on 10V (Y) of the 3 ways valve actuator
Connect NC contact (C and 2) of THA (Deicing Thermostat) on 5 and 6
Possibility to connect the circulator on the DO4 terminals of the regulator and the terminal block number 19.
(Note: 24V output to relay)
Batterie changeover : Install siphon on the drain evacuation
The changeover thermostat must be connected to the water inlet before Bypass.
You must cable 3 ways valve to the changeover thermostat.
Connect them following the instructions below :
Red wire to the changeover thermostat (CO) on 10V (Y) of the valve
Terminal 15 on +24V (G) of the 3 ways valve actuator
Terminal 16 on the 0V (G0) of the 3 ways valve actuator
Terminal 17 connected to the brown wire of the changeover thermostat (Heat signal)
Terminal 30 connected to the black wire of the changeover thermostat (Cold signal)
Connect the NC contact (C and 2) of THA (Deicing Thermostat) on 5 and 6
Possibility to connect the circulator on the DO3 terminal of the regulator and the terminal block 18 (heat demand) and on the
DO4 terminals of the regulator and the terminal block number 19 (cold demand ). (Note: 24V output to relay)
ATTENTION In this case use a relay for each exit and cable in parallel on the ON/OFF of the circulator.
