The Honeywell Motorised Valves have a wide range of flow control applications in domestic and light commercial central heating systems. The typically closed Honeywell variants feature end switches for pump and/or boiler electrical control.
The Zone Valve must be positioned where it cannot block any vent or cold feed when closed, it may be plumbed in at any angle but must not be mounted
If fitted in a confined space, sufficient ventilation must be available to keep the valve within its ambient temperature range and access must be provided to remove the powerhead if necessary
