morning when you are geng 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
me to --.— and the thermostat will ignore this seng.

Feature Setup
Feature 01 – Temperature Format: This funcon allows you to
select between °C or °F.
Feature 02 – Switching Differenal: This funcon allows you to
adjust the switching differenal 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 opmum
switching of the heang in your home. As an example, the default
is 1°C which means the thermostat will switch the heang 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 applicaons.
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 – UH1-W Address:Within one building, up to 9
UH1-W’s can be used, each must have a unique address.
Feature 06 - Zone No.
This is the zone number on the UH1-W you wish to assign the
thermostat to, select from 1-8.
Feature 07 – Under-floor Heang or Radiator Zone: This seng
determines whether the thermostat will acve the pump & boiler
outputs on the UH1-W when the thermostat calls for heat.
00-Enabled 01-Disabled.
Feature 08 – 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 acvate the output for 20% of the
me. This is to protect the system against a loss of wireless signal
or should the thermostat baery fail whilst you are away.
13

Feature 09 – Up/Down Temperature Limit
This funcon 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
heang system.
Feature 10 – Opmum Start: Opmum start will bring the heang
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 me when
programming the comfort levels. The thermostat will automacally
learn the required heat up me and will adjust itself, if required,
throughout the year.
Feature 11 – Rate of Change: This is the number of minutes the
thermostat has calculated it takes to raise your building 1°C. The
thermostat will connue to learn the heat up me of your home
and will adjust this seng to suit.
Feature 12 – 5/2 Day or 7 Day: This funcon 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.
