5. Specifications
Current rating: 16 (4) A
Voltage: 230V, 50HZ
Switch type: Single pole, double throw
(SPDT)
Operating
temperature range: 0 to 55°C
Set temperature
range: 40 to 80°C
Complies with: BS EN 60730
Conforms to
directives: 73-23-EEC, 89-336-EEC
Always isolate the mains supply before
starting work.
Incoming cable should be 1.5mmsq.
Remove cover from unit by unscrewing cover
retaining screw, and easing off the temperature
adjusting knob.
Thread incoming wire though the cable gland.
Allow sufficient excess cable to wire up the
unit, but not too much to make it difficult to
close the cover on the unit.
Connect the conductors to the relevant
terminals, according to the wiring diagram.
Ensure that the brass washer grips the conductor.
Pull some of the excess cable back through the
gland and then tighten the gland to trap the
cable and give good strain relief.
Replace the cover and the adjustment knob.
Adjust the length of the spring wire, and use it
to strap the TRT044 to the hot water cylinder.
Restore mains to the unit after checking all
system wiring is complete.

Operating & Installation Instructions
2. Siting
The TRT044 is designed to be surface mounted
onto the domestic hot water cylinder. For
cylinders with an insulating foam covering, a
section of foam must be removed so the back
of the thermostat is in direct contact with the
metal body of the tank.
The TRT044 should be mounted between a
quarter and third of the way up from the base
of the tank in a position that gives good access
to the dial.
3. Installation
This product must be installed in accordance
with the appropriate building and wiring
regulations.
In all cases if there is a doubt as to how to
proceed with an installation consult a qualified
electrician, your local authority’s building
control department or the Timeguard helpline
(020 8450 0515).

4. Operation
Use adjuster dial to set desired temperature.
For vulnerable people it may be advisable to
reduce the setting to as low as 50ºC bearing in
mind the outlet water temperature will be
somewhat higher than this due to the
temperature stratification in the tank.
To clean use a clean dry cloth only. Do not use
any liquid cleaners.

1. Introduction
TRT products are a cost effective
comprehensive range of thermostats and
controllers designed for internal use only.
The TRT044 is cylinderstat, with an easily
adjustable dial. It is designed to be
mounted to a domestic hot water
cylinder using a spring wire, and allows
the user to economically control the
temperature of the hot water. It can be
fitted to all hot water cylinders, or
alternatively it can be used as a pipestat
using the alternative wire strap supplied.
The TRT044 can be used to switch a
circulating pump, boiler, or most
common motorised zone valves. It can
also be used for switching domestic 13A
immersion heaters if required.
The electrical supply must be isolated
before attempting to install the TRT044.

TRT044 Cylinder/Pipe Thermostat
Side View
A cylinder thermostat switches on and off
the heat supply from the boiler to the
hot-water cylinder. It works by sensing the
temperature of the water inside the cylinder,
switching on the water heating when the
temperature falls below the thermostat
setting, and switching it off once this set
temperature has been reached.
Turning a cylinder thermostat to a higher
setting will not make the water heat up any
faster.
How quickly the water heats up depends
on the design of the heating system, for
example, the size of boiler and the heat
exchanger inside the cylinder.
The water heating will not work if a time
switch or programmer has switched it off.
And the cylinder thermostat will not
always switch the boiler off, because
the boiler sometimes needs to heat
the radiators.
Cylinder thermostats are usually fitted between one
quarter and one third of the way up the cyl-
inder. The cylinder thermostat will have a
temperature scale marked on it, and it
should be set at between 60ºC and 65ºC,
then left to do its job. This temperature is
high enough to kill off harmful bacteria in
the water, but raising the temperature of
the stored hot water any higher will result
in wasted energy and increase the risk of
scalding.
If you have a boiler control thermostat,
it should always be set to a higher
temperature than that of the cylinder
thermostat. In most boilers, a single boiler
thermostat controls the temperature of
water sent to both the cylinder and
radiators, although in some there are
two separate boiler thermostats.
