Drayton Wiser Valve

Introduction

Wiser Radiator Thermostats have a direct connection to the boiler, enabling you to control the on/off times and temperatures of individual rooms via the app.

The Wiser Radiator Thermostat is mounted on standard radiator valve bodies.
This is achieved by simply unscrewing the existing TRV head and replacing with the Wiser head. Hand tightening is sufficient, no tools should be used.
The Wiser Radiator Thermostat contains multiple sensors for accurate room temperature measurement.
Temperature schedules are set on the Wiser app but you can boost the schedule (to increase or decrease temperature) by twisting the top.
It is powered by 2 x AA batteries

Mounting the Wiser Radiator Thermostat

The Wiser Radiator Thermostat is supplied with 2 valve adapters which cover 95% of TRVs used in the UK (see below)
The most common thermostatic valves have a M30 x 1.5mm connection
These include the current TRVs from brands such as Drayton, Honeywell, Pegler, Myson and Siemens
The M30 valve adapter and chrome ring nut should be used
Less often you may find a Danfoss RA valve. The Danfoss adapter included in the box should be used (see above)

Mounting the Radiator Thermostat on alternative valve body type

For other valves, a different adapter will be needed.
These are available from sources such as www.conrad-electronic.co.uk
The thermostat/valve adapter is attached to the valve and the M30 adapter and chrome ring nut (provided in the box) are used to screw the Wiser Radiator Thermostat in place.
