Sequence of Operation / Settings

Priority Jumper: OFF

Master/Slave Jumper: Master

Status During Priority: OFF

•

A demand occurs from a T-stat (T-stat

closes TT terminals) in zones 2 thru 6 otr the

aquastat on zone #1. The “T-STAT CALL” LED

illuminates for that zone.

•

ZVR control sends 24 VAC to the corresponding

zone MOTOR terminals to open the zone

valve.

•

When the end switch on the zone valve closes,

the control sends 120 VAC to SEC PUMP and

SYSTEM PUMP. The “VALVE OPEN” LED

illuminates for that zone and the XX contacts

close to signal a heat demand to the boiler.

•

When the demand from the T-stat is satisfied

(T-stat opens TT terminals), both the “T-STAT

CALL” and “VALVE OPEN” LED’s turn off.

•

24 VAC is dropped from the corresponding

zone MOTOR terminals.

•

If no other zones are calling, power is turned

off to the SEC PUMP and SYSTEM PUMP and

the XX contacts are opened.

Description of terminals

= Ground

= Neutral (common leg of 120 VAC)

= Line (live leg of 120 VAC)

Thermostat terminals

R = 24 VAC
W = Heat call
C = Common of 24 VAC

Boiler terminals

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.

Pump terminals

SYSTEM PUMP = Runs when any zone calls for

heat. When priority is enabled, the status of the

pump (on\off) during a priority call is selected via

a jumper
SEC PUMP = Runs when any zone calls for heat

except the priority zone when it is enabled.
PRIORITY PUMP = Runs when the priority zone

calls. A jumper is required between the END

SWITCH terminals when using a pump.

Valve terminals

Motor = 24 VAC to power the zone valve motor
End Switch = Connects to end switch on zone

valve. Must be jumpered if using a 2 –wire zone

valve.

WARNING:

NEVER CONNECT R & C DIRECTLY,

this will be a direct short on the 24 VAC supply
