1. Introduction
This manual provides essential information for the safe and effective installation, operation, and maintenance of your Dimplex XT9605 Charge Control Thermostat. This thermostat is specifically designed as a replacement for older, larger thermostats found in Dimplex XL storage heaters manufactured before October 2001. Please read these instructions thoroughly before proceeding with any installation or operation.
1.1 Safety Information
- Always disconnect the main power supply to the storage heater before attempting any installation, maintenance, or repair work. Failure to do so can result in electric shock or serious injury.
- Installation should only be performed by a qualified electrician or competent person.
- Ensure all connections are secure and comply with local wiring regulations.
- Do not operate the thermostat if it appears damaged.
2. Setup and Installation
The Dimplex XT9605 thermostat is designed for straightforward replacement of existing units. It comes with new fixings, which may have different thread types than your old thermostat. Exercise caution and do not force connections.
2.1 Preparation
- Disconnect Power: Locate the main power switch for your Dimplex XL storage heater and turn it OFF. Verify that the power is off using a suitable voltage tester.
- Access Thermostat: Carefully remove the outer casing or access panel of your storage heater to expose the existing thermostat. Refer to your specific heater's manual for detailed access instructions.
2.2 Replacement Procedure
- Remove Old Thermostat: Disconnect the wiring from the old thermostat, noting the position of each wire. It is recommended to take a photograph before disconnecting. Unscrew and remove the old thermostat.
- Install New Thermostat: Position the new Dimplex XT9605 thermostat in the designated location. Use the provided new fixings to secure it. Ensure the thermostat is firmly mounted.
- Connect Wiring: Reconnect the wiring to the new thermostat according to the previous configuration. Double-check all connections for tightness and correctness.

2.3 Final Steps
- Reassemble Heater: Replace the access panel or outer casing of the storage heater, ensuring all screws are tightened.
- Restore Power: Turn the main power supply to the storage heater back ON.
- Test Operation: Proceed to the Operating section to test the thermostat's functionality.
3. Operating Instructions
The Dimplex XT9605 thermostat controls the charge level of your Dimplex XL storage heater, influencing how much heat is stored during off-peak hours. The thermostat features a push-button type controller for setting adjustments.

3.1 Setting the Charge Level
The specific method for adjusting the charge level will depend on the design of your Dimplex XL heater's control panel, which interacts with this thermostat. Generally, you will find a dial or button on the heater's fascia that corresponds to the thermostat's setting. Consult your heater's user manual for precise instructions on how to adjust the charge control.
- A higher setting typically results in more heat stored, providing warmth for a longer duration.
- A lower setting results in less heat stored, which can save energy if less heat is required.
Allow time for the heater to cycle through a full charge period (usually overnight) to observe the effect of any adjustments.
4. Maintenance
The Dimplex XT9605 Charge Control Thermostat is designed for reliable operation and requires minimal maintenance. Regular checks of the storage heater itself are recommended.
- Cleaning: Ensure the area around the thermostat within the heater is free from dust and debris. Always disconnect power before cleaning.
- Visual Inspection: Periodically inspect the thermostat and its wiring for any signs of damage, loose connections, or overheating. If any issues are observed, disconnect power and consult a qualified technician.
5. Troubleshooting
If your Dimplex XL storage heater is not functioning as expected after thermostat replacement, consider the following:
- No Heat/Insufficient Heat:
- Power Supply: Ensure the main power supply to the heater is ON.
- Thermostat Setting: Verify that the charge control setting on your heater is not set too low.
- Wiring: Double-check all wiring connections to the thermostat for correctness and tightness. Loose connections can prevent proper operation.
- Overheating:
- Thermostat Setting: Ensure the charge control setting is not excessively high for your heating needs.
- Thermostat Fault: If the heater consistently overheats regardless of settings, the thermostat may be faulty and require replacement.
- Physical Damage: If the thermostat or its components appear physically damaged, it must be replaced.
For persistent issues, it is recommended to contact a qualified electrician or the manufacturer for assistance.
