Optional Features Explained
THE FOLLOWING SETTINGS ARE OPTIONAL AND IN MOST CASES
NEED NOT BE ADJUSTED
Feature 01 - Temperature Format:
This function allows you to select between °C and °F.
Feature 02 – Switching Differential:
This function allows you to increase the switching
differential of the thermostat. The default is 1°C which means that with a set temperature
of 20°C, the thermostat will switch the heating on at 19°C and off at 20°C. With a 2°C
differential, the heating will switch on at 18°C and off at 20°C.
Feature 03 – Frost Protect:
You can set whether the thermostat will maintain the frost
temperature when the thermostat display is turned off. As a default, this is enabled.
Feature 04 – Frost Protect Temperature:
This is the temperature maintained when the
thermostat is in frost mode. The range is 07-17°C. The default is 12°C and is suitable for
most applications.
Feature 05 – Output Delay:
To prevent rapid switching, and output delay can be entered.
This can be set from 00 - 15 minutes. The default is 00 which means there is no delay.
Feature 06 – UH1-W or RC1-W receiver:
The thermostat can work with our UH1-W 8 zone
wiring centre or RC1-W 2 channel receiver. This setting determines which is being used.
Feature 07 – Receiver Address:
Within one building, up to 9 UH1-W’s or 32 RC1-W’s can
be used. Each receiver must have a unique receiver address.
Feature 08 – Zone Number:
This is the zone number you are assigning the thermostat to
on either the UH1-W or the RC1-W receiver. 01 - 08 - UH1-W, 01 - 02 – RC1-W
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
and in case the thermostat battery fails whilst you are away.
Feature 11 – Up/Down Temperature Limit:
This function allows you to limit the use of
the up and down keys. This limit is also applicable when the thermostat is locked and
so allows you to give others limited control of the heating system.
Feature 12 – Air Sensor Selection:
On this thermostat, you can select which sensor
should be used - built in sensor or remote air sensor.
Feature 13 – Not used on this model
Feature 14 – Optimum Start:
Optimum start will delay the start up of the heating
system to the latest possible moment to avoid unnecessary heating and ensure the
building is warm at the programmed time. The thermostat uses the rate of change
information to calculate how long the heating needs to raise the building temperature
1°C (with a rate of change of 20, the thermostat has calculated the heating needs 20
minutes to raise the building temperature 1°C) and starts the heating accordingly.
Feature 15 - Rate of Change:
For information only.
Feature 16 - Programming Mode:
The thermostat offers two programming methods.
Weekday/Weekend allows you to program 4 comfort levels for the weekdays and 4
different comfort levels for the weekend. In 7 day program mode, each day has 4
comfort levels that can be programmed independently.
