Two Zone Valve Controls operate six heating zones and a domestic hot water tank. When a thermostat calls for heat, the zone valve opens. The hot water tank is heated using a pump when the tank aquastat calls for heat. The master control operates the system pump and the boiler when there is a call for heat on either the master or member control.

User Interface - Indicator LED

Power

• On when 115 V (ac) is applied.

• Off when power disconnected or transformer fuse is blown.

Priority

• On when zone 1 has priority over zones 2 and 3.

• Flashing while in priority override.

RoomResponse

• On when modulating condensing boiler is operating below maximum setting.

System Pump

• On when zone valve end switches are closed (valve open).

• Off when zone valve end switches are open circuit (valve closed).

Sequence of Operation

Zone 1 Call

• On when thermostat 1 calls for heat.

• Off when thermostat 1 stops calling for heat.

Zones 2 and 3 Call

• On when the corresponding thermostat calls for heat.

• Off during priority operation.

• Off when corresponding thermostat stops calling for heat.

Zones 1 to 3 Valve Open

• On when corresponding thermostat calls for heat and the zone valve is open (end switch closed).

• Off when zone valve closed (end switch open circuit).

• Off when corresponding thermostat stops calling for heat.

Zone Operation

When a thermostat calls for heat by closing the R and W terminals:

• 24 V (ac) is applied to the corresponding zone valve.

• The corresponding zone indicator LED is turned on.

Boiler Operation

When a thermostat calls for heat by closing the R and W terminals:

• The boiler end switch XX is closed to fire the boiler. This requires the control DIP switch to be set to Maste r.

• The RoomResponseTM 0-10 V (dc) or 4-20 mA signal is sent to a modulating-condensing boiler.

DHW Operation

Many modulating-condensing boilers have multiple temperature call inputs. Wire the DHW end switch to input recommended in the boiler’s manual.

When a zone 1 calls for heat by closing the R and W terminals:

• The DHW end switch is closed to fire the boiler at the DHW temperature.

• The Mod Boiler output is changed to 10 V (dc) or 20 mA.

Priority Override

• The Priority LED light flashes when priority override is in effect.

• Priority for zone 1 is in effect for 60 minutes after which priority override starts by shutting off zone 1 and resumes heating on zones 2 and 3 and expansion zones.

• During priority override, the mod max dial setting limits the RoomResponseTM signal to the boiler.

Master / Member DIP Switch

• Allows for unlimited expansion using additional Switching Relays and/or Zone Valve Controls.

• The Master Switching Relay is wired and operates the boiler.

• If using a single Switching Relay set to Master.

• When using multiple Switching Relays and/or Zone Valve Controls, set one control to Master and set all other controls to Member.

• The boiler end switch XX only closes when the DIP switch is set to Master and does not close when set to Member.

T-Stat 1 Priority DIP Switch

When T-Stat 1 is calling for heat by closing the R and W terminals:

• 115 V (ac) is applied to the Priority Pump 1.

• Zone 1 indicator LED is turned on.

• Priority indicator LED is turned on.

• Zones 2 and 3 zone valves and LEDs are turned off.

• Expansion Member controls shut off their zones.

• After 60 minutes of continuous zone 1 call for DHW heating the control goes into priority override. This prevents building freeze up if the DHW tank aquastat fails in the closed position.

• A jumper wire must be installed on the zone 1 end switch if a pump is installed and the Zone Valve End Switches DIP switch is set on.

Exercising DIP Switch

• ON: Each circulator pump is energized for 30 seconds every 72 hours.

• OFF: Circulator pump exercising disabled.

Post Purge DIP Switch

• ON: After thermostat 1 stops calling for heat, the zone 1 priority pump and zone valve remain on for 2 minutes to purge heat from the boiler to the zone.

• OFF: Post purge disabled.

Mod Boiler DIP Switch

Select either 0-10 V (dc) or 4-20 mA signal to the modulating condensing boiler. Consult the boiler manual to determine the signal type. The DIP switch position does not matter if the modulating boiler output is not used.

System Pump During Priority DIP Switch

• On: System pump operates when zone 1 calls for heat.

• Off: System pump shuts off when zone 1 calls for heat. Typically set off when using a pump for heating a domestic hot water tank.

System Pump With Member Call DIP Switch

• On: System pump on the master control runs when a zone on a member control calls for heat.

• Off: System pump on the master control does not turn on when a zone on a member control calls for heat.

Zone Valve End Switches DIP Switch

• On: System pump and boiler will not turn on until the zone valve end switch is closed. Select this option when using 3 or 4-wire zone valves.

• Off: System pump and boiler turn on immediately when a thermostat calls for heat. Select this option when using 2-wire zone valves.

Fuses

• All fuses are T5A 250V slow blow, glass 5 x 20 mm.

• Fuses 1 and 2 correspond to the 24 V (ac) transformer power supply. If a fuse is blown, first check that the thermostat wiring is not shorted. Then replace the fuse.

RoomResponseTM Signal

The RoomResponseTM signal adjusts the temperature of a modulating condensing boiler that accepts a 0-10 V(dc) or 4-20 mA input. It works by continually adjusting boiler water temperatures to the lowest possible value to meet comfort without wasting energy. This is done by monitoring each thermostat's on and off time pattern and determines the ideal water temperature for each zone. The control then chooses the highest water temperature requirement of all the thermostats and provides a 0-10 V (dc) or 4-20 mA signal proportional to the boiler operating temperature. The RoomResponseTM signal is a DOE compliant method of controlling boiler temperature to building load. The RoomResponseTM signal is not available to on/off boilers. Benefits of the RoomResponseTM signal include:

• Increase in boiler efficiency

• Reduction in room temperature swing

• Reduction in expansion noises from heating pipes
