Wiring a standard zone valve to Calef Z-one Relay
Since a two wire actuator does not have an end switch for feedback
to the ZVR control, the end switch terminals must have a jumper to
simulate the end switch. If the end switch jumper is not installed, no
demand will be sent to the boiler and the pumps will not turn on
.
Wiring a Taco 570 valve to Calef Z-one Relay
When connecting the Taco 570 zone valve to the Caleffi Z-one Relay,
the wiring of this valve can only be done in one way. The left motor
terminal on the ZVR series control must be connected to terminal 2
on the zone valve. The right motor terminal must be connected to
terminal 1 on the zone valve. Lastly, the left end switch terminal
must be connected to terminal 3 on the zone valve. Failure to follow
schematic will lead to damage of product.
Wiring a White Rogers 1361 valve to Calef Z-one Relay
The White Rogers 1361 zone valve requires 24 VAC to terminal 2
at all times, therefor connect to the R terminal of the associated
T-STAT on the ZVR control. The left motor terminal on the ZVR
series control must be connected to terminal 4 on the zone valve.
The right motor terminal must be connected to terminal 1 on the
zone valve. Lastly, the left end switch terminal must be connected
to terminal 3 on the zone valve. The 1361 can not be used on any
zone when the ZVR control is set for priority.
