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 or °F.
Feature 02 - Switching Differential:
This function allows you to increase the switching
differential of the thermostat. The default is 1°C which means the thermostat will
switch the heating on 1°C below the set temperature and will turn it off when the set
temperature is achieved. With a 2°C differential, the heating will switch on 2°C below the
set temperature and will switch off when the set temperature is achieved.
Feature 03 - Frost Protect:
This is the temperature maintained when the thermostat
is in frost mode. The range is 07-17
o
C. The default is 12
o
C and is most suitable for most
applications.
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 in case the thermostat battery fails whilst you are away.
Feature 07 – 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 08 – Rate Of Change:
This is the number of minutes the thermostat has
calculated it takes to raise your building temperature 1°C. The thermostat will
continue to monitor and learn the heat up time of your home to optimise heating
efficiency.
Feature 09 - Programming Mode:
The thermostat offers 2 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.
Feature 10 – Floor Limit Temperature:
This thermostat uses the floor limiting sensor
connected to the receiver to protect the floor surface from overheating. The floor
limit is set from the thermostat but stored in the receiver.
Should the RF link fail, the receiver will limit the floor from overheating.
The limit can be adjusted from 20-45
