Control solutions for PACi

Interface to run 2 or 3 PACi and VRF indoor units. PAW-PACR3

In combination with one PAW-T10 on each indoor unit, allows the redundant operation of 2 (or 3) PACi or VRF indoor units.
All units will be operated sequentially in order to achieve the same operating time (example turn every 8 hours within a 24 hour period).
If the room temperature exceeds a freely set value, the 2nd (or 3rd) unit will be switched ON and an alarm will be activated.
