WHAT IS THE LUNASTAT?
The LunaStat is a multi-function thermostat/timer for any part of
your heating or hot water system where thermostatic or
programmable control is required
The LunaStat consists of three main modes:
1. Standalone programmable/non-programmable thermostat
2. Setback thermostat with central programmer
3. Single channel timer

PROGRAMMABLE/NON-PROGRAMMABLE THERMOSTAT
1. PROGRAMMABLE/NON-PROGRAMMABLE THERMOSTAT
The LunaStat operates by itself as independent control to the
rest of the heating system as a thermostat in either
programmable or non-programmable operation.
A. Non-programmable – operates as a simple thermostat where
the temperature is held at the set point continuously.
B. Programmable – operates as a fully programmable thermostat
with 4 times at which to set a target temperature. This enables
you to regulate the temperature in your home by setting
specific temperatures for times of day.
This way the thermostat doesn’t operate the heating as On/Off
but as an Up/Down control to the specific temperatures you set
on your LunaStat.
This enables you to have intricate control in each room creating
a micro climate in different areas of your home and regulating
the temperature for night, for when your home is unoccupied,
or even when individual rooms are unoccupied or not used.

SETBACK THERMOSTAT WITH CENTRAL PROGRAMMER
2. SETBACK THERMOSTAT WITH CENTRAL PROGRAMMER
The LunaStat operates as temperature control on a room by
room basis in conjunction with a single programmer (supplied
separately) providing central timed control for larger areas or
whole houses.
The LunaStat is set to non-programmable and maintains the
temperature at the set point whilst the programmer is on. When
the programmer is off the LunaStat automatically drops the set
temperature by up to 5oC for example during the night or whilst
the property is unoccupied.
This enables the operation of an efficient system with simple to
use thermostat and central programmer rather than multiple
thermostats that need programming one at a time.

6
SINGLE CHANNEL TIMER
3. SINGLE CHANNEL TIMER
The LunaStat operates by itself as 8am independent timer
control for any part of your heating or hot water system.
This enables you to have accurate timer control of your heating
and hot water system, with the LunaStat ensuring the system
operates at the time you require and set, available in 5 minute
increments.

7
INSTALLATION PROCEDURE
Care should be taken on where the LunaStat is installed as being the
ultimate control of your heating it is important that it is not installed
near any secondary hot or cold sources. The LunaStat should be
installed at chest/eye level and where it will receive an even reading
of the temperature of the room. It should be installed out of direct
sunlight, away from draft or heat sources such as airing cupboards.
The LunaStat is designed to be mounted flush and will require an
electrical back box with a depth of at least 35mm.
INSTALLATION PROCEDURE
Step 1
Separate the two halves of the
thermostat by using a small flat
screwdriver to disengage the
clips in the top edge of the
LunaStat.
Step 2
Ensure that the front (Screen)
part of the thermostat is kept
somewhere safe and clean.
Terminate the cable for the
thermostat in accordance with
wiring diagrams on pages 48-51.
Step 3
Fix the thermostat back plate
back to the back box with the
screws provided, ensuring this
is secure.
Step 4
Clip the front on to the back
plate engaging the bottom
clips first.
