when you are getting ready for work, cooler during the day when the
house is unoccupied and then warmer in the evening when you are
at home relaxing. The thermostat offers 5/2 Day Programming (4
Levels for the Weekday, 4 for the Weekend) and 7 Day Programming
(4 Levels for each day)
Tip- If you don’t want to use all of the comfort levels, just set the
time to --.—and the thermostat will ignore this setting.

Feature Setup
Feature 01 –Temperature Format: This function allows you to select
between °C or °F
Feature 02 –Switching Differential: This function allows you to
adjust the switching differential of the thermostat. This is the number
of degrees the thermostat will switch on below the set temperature.
This can be adjusted in order to obtain optimum switching of the
heating in your home. As an example, the default is 1°C which means
the thermostat will switch the heating on 1.0°C below the set
temperature.
Feature 03 –Frost 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 almost all applications.
12

Feature 04 –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 05 –Pairing Function: Allows the thermostat to be paired
with the receiver.
Feature 06 - Fail Safe
If enabled, the thermostat will send a signal to the receiver every 20
minutes. Should the receiver fail to receive the signal from the
thermostat, 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 07 –Optimum Start: Optimum start will bring the heating
on early if needed, so the house is warm when you wake up. This
means you don’t need to allow any extra heat up time when
programming the comfort levels. The thermostat will automatically
learn the required heat up time and will adjust itself, if required,
throughout the year. 13

Feature 08 –Rate of Change: This is the number of minutes the
thermostat has calculated it takes to raise your building 1°C The
thermostat will continue to learn the heat up time of your home and
will adjust this setting to suit.
Feature 09 –5/2 Day or 7 Day: This function allows you to switch
between 5/2 day or 7 day programming. 5/2 Day means you can
program 4 comfort levels for the weekday and 4 different levels for
the weekend. 7 day programming allows you to program 4
temperature levels for each day of the week.
