Page: 31 / 40

Feature 09 – Underfloor Heating or Radiator Zone
(UH1-W Only): This setting determines whether the
thermostat will activate the pump & boiler output on the
UH1-W. If set to 00 the outputs will be activated.
00 = UFH, 01 = Radiators
Feature 10 – Fail Safe: If enabled, the thermostat will
send a signal to the receiver every 20 minutes. Should the
receiver fail to receive two signals, the receiver will activate
the output for 20% of the time. This is to protect the system
against a loss of wireless signal or should the thermostat
battery fail whilst you are away.
Feature 11 – Temperature Up/Down Limit: This function
allows you to limit the use of the up and down temperature
arrow keys. This limit is also applicable when the thermostat
is locked and so allows you to give others limited control
over the heating system.
Feature 12 - Sensor Selection: On this thermostat you can
select to use the built in sensor (00) or remote air sensor (01).
Feature 13 – Floor Limit Sensor: This function does not
apply to this model.
