INSTALLATION & OPERATING INSTRUCTIONS

General

The ProgramaSTAT TPT44 combines the elements of
timeswitch and room thermostat in a single compact,
economical and stylish unit. Back up is provided to
retain programme information in the event of a
power failure.

The TPT44 controls the room temperature to a
comfort level when required and to a set-back
temperature at other times. It does this using
an internal temperature sensor. The set-back
temperature can be set to 10°C for frost protection
or much higher when elderly or infirm are occupying
the room. The floor temperature is monitored with
an underfloor probe (included) and is limited at
a user adjustable temperature which must not
be set higher than 30°C.

Siting

The TPT44 ProgramaSTAT should not be installed in
a wet area. Further siting instructions are given in
the Thermolay cable and mat instruction leaflet.
If there is additional heating in the room do not
position the TPT44 directly above it.

Installation

We recommend this unit be fitted by a
qualified electrician.

Install in accordance with wiring and current
building regulations.

Please read the instructions carefully. If in doubt,
contact the Timeguard Helpline 020 8450 0515.

The TPT44 underfloor heating controller is designed
to fit onto either a BS4662 recessed single box or a
BS5733 surface mount single box. The minimum box
depth required is 32mm. The ideal mounting height
is at eye level for the shortest person who is likely
to programme the unit. For details of the installation
of the temperature probe and heating cable or mat
see the Thermolay instruction leaflet.

Switch OFF the mains to the controller.
Remove the thermostat surround by pulling
forward on the surround. Use a small screwdriver as
a lever to remove the surround when the thermostat is
fixed on the wall. Cut the cable tails of the temperature
probe and heating mat or cables to length and strip
sleeving and insulation as required. Identify the wires
and locate according to figure 1. Supply cable with
a minimum of 2.5mm
screw terminals onto the wires and form the cables.

Ensure that the link shown between terminals 2
and 3 in Fig. 1 is in place. Offer the unit up to the

wall box forming the cables as required, finally locating
and tightening up the fixing screws supplied.
Snap the surround back into position.

To test the unit is operating set the temperature to
30ºC as described in

must be used. Tighten the

‘

Manual Temperature Setting A.

Temporary temperature override’. After a few seconds
the Heating ON indicator will show. Wait for 1 hour for
a wood under floor or up to 5 hours for an uninsulated
concrete floor (the warm-up time for uninsulated
concrete will be substantially reduced when the moisture
has been driven out of the concrete during the first few
heating cycles) and feel if the floor starts to warm.
If it does not, check the connections and carry out

the checks on the mat or cable installation instructions.
