THE FOLLOWING SETTINGS ARE OPTIONAL AND IN MOST CASES

NEED NOT BE ADJUSTED

Optional Features Explained

Feature 01 – Temperature Format: This function allows you to select between C/F

Feature 02 - Switching Differential: This function allows you to increase the switching differential of the thermostat. The default is 1C which means that with a set temperature of 20C, the thermostat will switch the heating on at 19C and off at 20C. With a 2C differential, the heating will switch on at 18C and off at 20C

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

17

Feature 04 – Frost Protect Temperature: This is the temperature maintained when the thermostat is in frost mode.

The range is 07-17C. The default is 12C and is suitable for almost all applications.

Feature 05 – Output Delay: To prevent rapid switching, an 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-RF or Standalone Receiver: The thermostat can work with our UH1 or standalone receiver. This setting determines which is being used.

Feature 07 – Receiver Address: Within one building, up to 9

UH1s or 32 standalone receivers can be used. Each receiver must have a unique receiver address.

18

Feature 08 – Zone Number: This zone number relates to either the zone number on the accompanying UH1 or the standalone receiver.

Feature 09 – Underfloor Heating or Radiator Zone (UH1 Only):

This setting determines whether the thermostat will active the pump relay on the UH1

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.

19

Feature 11 – Up/Down Temperature Limit

This function allows you to limit the use of the up and down temperature 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 – Not used on this model

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, so that the dwelling is comfortably warm by the programmed time. The thermostat uses the rate of change (see below) setting to calculate how long the building needs to take to raise the building 1C (with a rate of change of

20, the thermostat has calculated the building needs 20 minutes to raise the building 1C)

20

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 weekday and 4 different comfort levels for the weekend. In 7 day program mode, each day has 4 comfort levels that can be programmed independently.
