- Flush mounting
- 0°C / 0°F Selectable
- Key Locking Facility
- Frost protection with adjustable temperature setting
- Easily increase or decrease the required temperature
- Remote control optional
- Supply: 230v / 110v option
- Outputs: Volt free 3A Maximum
- Dimensions: 98mm x 85mm x 13mm (Height, Width, Depth) - Note 13mm depth is after installation
Programmable versus Non Programmable?
We would always suggest that you consider using a programmable thermostat as it gives overall better level of control, allowing you to set the various comfort levels throughout the day. For those wanting a simple digital thermostat, then the DT model is fine. The Heatmiser DT features key-lock allowing you to control the system with ease.
Mounting?
This thermostat is flush mounting, and therefore requires a back box sunk in the wall to accommodate the terminal box for the thermostat. We suggest a back box of 35mm.
Frequently Asked Questions?
Q - Can I replace my existing mechanical thermostat with the Heatmiser DT?
A - You need to check the number of wires you have behind your existing thermostat. If you have three, not counting the earth, then the DT can be used as a replacement. You should note that the DT will be powered from your existing timeclock, and therefore the display will go blank during the timed off periods.
Q - I only have two wires, do you have an alternative thermostat?
A - Unfortunately not. All our thermostats are mains powered and so this would require three wires minimum.
Q - I have checked and I do have three wires, can you explain what these are?
A - These wires are known as Live (Red), Neutral (Blue) and Switch Live (Yellow) The Live and Neutral is used to power the thermostat. The switch wire becomes live when there is a demand for heat (You should always check the colour coding used by the original installer).
Q - I have a combi boiler. Can I use this thermostat?
A - Yes, you would have two connections from the boiler which would connect across our A1, A2 terminals. Live and Neutral would be connected as usual (4 wires required for this installation).
Terminal Options:
Standard 230v - Select this terminal output if your supply power is 230v and you require a switch live or boiler control circuit. You should have 3 or 4 wires at the thermostat (not counting earth).
Changeover - Select this terminal output if your supply power is 230v and you have a valve that needs power to open, and power to close.
Standard 110v - Select this terminal output if your supply power is 110v and you require a switch live or boiler control circuit.
