Wilo

The Wilo - Comfort twin pump pressurisation units (duty / standby) are engineered for use on heating or chilled water systems up to and including 3.5 bar. Cold fill pressures.

The unit is fitted with an 18 litre polypropylene break tank c/w type AB air gap to BS13077:2008 and water regulations 1999, Wras approved equilibrium ball float valve to BS1212 and a low water float switch and strainers for pump protection.

Each pump is fitted with a non return valve and quick release couplings for ease of maintenance. The pressure transducer monitors the system pressure and feeds a 0-10v signal to the comfort controller.

Comfort Controller is complete with the following incorporates:

User friendly interface that has a 2 line LCD backlight display, Healthy / fail LED, Password protection, System Fill for initial fill of system, Pump check routine, that runs both pumps for 2 seconds if inactive for 7-90 days, Pump trip and fail alarms, System leak alarm, Excessive starts alarm, Alarm log, Hours Run, Automatic duty rotation, and Connectivity: BACnet = RS485 interface, BACnet MS/TP protocol.

2 wire BACnet

Volt Free Contacts are supplied with terminals for common, normally open and normally closed.

(5A, 230V)

Pump no.1 trip, Pump no. 1 run, Pump no.2 trip, Pump no. 2 run, High Pressure, Low Pressure, Excess starts, Low water and Boiler Interlock (NC only)

(10A, 230V)
