The AT-WFM can directly control two AT-V-P-xx or AT-V-B-xx solenoid valves only. The valves should be connected as shown above.
The valve should be connected to the same channel as the water meter. If two channels are being used with only one valve (standard
BREEAM setup) the valve should be connected to channel 2 (internal).
If using AT-V-xx or AT-BV-xx butterfly or ball valves an AT-RU1 valve controller must be used. Please see the connection diagram below.
