4. 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 temperature adjustment knob.

7. Operation
• Use the temperature adjustment knob to set the desired temperature.
Note: For vulnerable people it may be advisable to reduce the setting
to as low as +50°C bearing in mind the outlet water temperature
will be somewhat higher than this due to the temperature stratification
in the tank.
