:
XX = Dry contacts rated up to 120 VAC, 2 Amps.
Closes when any zone calls including priority. Typically
connected to TT on boiler control.
DHW (ZR/ZC) = Dry contacts rated up to 120 VAC, 2
Amps. Closes only when priority is enabled and calling.
Typically used to close ZR\ZC (120 VAC) or DHW contacts (24 VAC) on boiler
controls equipped with these features.
Communication connections:
Connect terminals to matching terminal of slave boards

Primary pump output:
Primary pump runs when any zone pump runs. Its status
during priority (on\off) can be programmed using the DIP
switches.

When connecting 2 or more Z-one controls, all controls must be powered by
the same 120 VAC circuit.
The DIP Switches on the ZSR series
can be positioned for the following
operations.
Master / Slave:
allows for unlimited
expansion to additional ZSR relays.
Priority OFF / Priority ON:
When
priority mode is ON, upon demand,
zone 1 will operate as priority and all other zones are temporarily switched off

When primary mode is ON, the primary pump will
continue to operate during priority.
Exercise OFF / Exercise ON:
When exercise mode is ON, each circulator is
switched on for 30 seconds following 72 hours of inactivity.
