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 2 must be used. Tighten the
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 ‘Manual Temperature Setting A.
