valve adapter guide
Wiser Radiator Thermsotats 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
