1 1. General description 2. Special features The Grundfos UPZC series of zone controls is the ideal choice for single- and multiple-zone hydronic heating systems using either zone pumps or low-voltage zone valves. Grundfos UPZC zone controls offer these features: Compatibility with 2-, 3-, and 4-wire, low-voltage controllers or thermostats. Wiring ease with 120 VAC, ground and low-voltage screw terminal inputs. Front-facing LEDs on the front. Side-mounted terminal connections for ease of wiring and installation. General description UPZC TM06 6569 1816 Additional features, UPZCP-3, -4, -6 Fig. 1 UPZC zone controls All Grundfos UPZC multiple-zone controls are expandable to handle any size of job. UPZC zone controls can control boiler pumps, domestic hot-water pumps, and system pumps and assign priority. The side-mounted terminals provide easy access and ease in wiring. The front-facing, easy-to-read LEDs on the front panel provide essential operating status. Grundfos UPZCP-3, -4, -6 zone controls offer these additional features: Pump exercise, selectable for 72 hours or 14 days – The pumps are turned on for 30 seconds every 72 hours or 14 days in order to prevent the pumps from seizing up. This feature only works if there is a jumper connecting the ZR-ZC terminals on the pump controller. Post-purge for pump controllers. After the priority zone calls for heat, the priority pump will be allowed to run for an additional two minutes after the thermostat contacts open. This allows some of the residual heat in the boiler to be transferred to the water. Boiler demand terminals – The two terminals, labeled "XX MAIN", are wired to the boiler. When the contacts close, the boiler starts and reaches a preset temperature for hydronic heating. DHW terminal – The two terminals, labeled "XX PRIORITY", are wired to the boiler. When the contacts close, the boiler starts and reaches a preset temperature for domestic hot-water heating. ZR-ZC terminals – The terminals are available on the pump controllers only. These terminals are connected by a jumper at the factory. The ZR terminal is always powered with 120 VAC. When you remove the jumper, all 120 V power is removed from the pumps. 3
3 UPZC Applications Additional features, UPZCV-3, -4, -6 Grundfos UPZCV-3, -4, -6 zone controls offer these additional features: Low-voltage, end-switch output terminals for the zone valves Replaceable, snap-fit 40 VA transformer for the zone valve controllers only Zone priority with selectable time-out feature Pump exercise, selectable for 72 hours or 14 days – The pumps are turned on for 30 seconds every 72 hours or 14 days in order to prevent the pumps from seizing up. Boiler demand terminals – The two terminals, labeled "XX MAIN", are wired to the boiler. When the contacts close, the boiler starts and reaches a preset temperature for hydronic heating. DHW terminal – The two terminals, labeled "XX PRIORITY", are wired to the boiler. When the contacts close, the boiler starts and reaches a preset temperature for domestic hot-water heating. 3. Applications Grundfos UPZC zone controls are for single- and multiple-zone, domestic, hydronic heating systems: UPZCP-1 For single-zone pump control. UPZCP-3, -4, -6 For multiple-zone pump control. UPZCV-3, -4, -6 For multiple-zone valve control. 4 4. Identification Nameplate The nameplate on the front of the product shows the model, part number, and required electrical input.

When connecting two or more controllers: You can only use the master controller with priority. When priority calls, the master board will produce 5 VDC between terminals B and C. This tells the slave board to turn off any zones that are calling for heat. This will also close the contacts "XX PRIORITY". When there is a demand for heat, the slave board will produce 5 VDC between terminals A and C. This tells the master board to activate any boiler or secondary pumps and close the contacts "XX MAIN". You can connect the pump and valve boards. When the slave board calls for heat, the secondary pump will be powered. If a boiler pump and secondary pump are to be used, they must be connected to the same terminals. You can use the low voltage wire to connect ABC terminals. The 120 VAC power supply must be connected to each board. The L and N terminals must be connected the same way on each board. If switched, a differential of 240 VAC can occur resulting in damage to the equipment.
