Brivis GDH Digital 24V Heat Only Manual Thermostat V2

This Brivis GDH Digital 24V Manual Thermostat (Version 2) is a straight-up, heat-only controller designed for Brivis ducted gas heating systems. It’s ideal for installs where you just need reliable warmth and simple operation without all the extra programming bells and whistles.

Sometimes, keeping it simple is best, especially for rental properties or zones where a set-and-forget approach works. You don't want call-backs because the user can't figure out their controller.

Best For

• Residential ducted gas heating installations and replacements.
• Service and maintenance teams working on Brivis GDH units.
• Property managers needing reliable, easy-to-use heating controls.
• Competent DIY owners replacing an existing Brivis manual thermostat.

Compatibility

This Brivis Manual Thermostat is specifically designed for 24V heat-only ducted gas heating systems, particularly Brivis GDH models. It's a Version 2 digital unit, ensuring compatibility with relevant Brivis control boards. If you're running a different model or brand, check fittings and specs before ordering.

Features

• Simple Operation: Straightforward controls mean easy temperature adjustment without complex programming.
• Large LCD Display: Clear, easy-to-read digital screen ensures current settings are visible at a glance.
• Heat Only Functionality: Dedicated for ducted gas heating systems, avoiding confusion with cooling modes.
• 24V Low Voltage: Standard wiring for safe and reliable operation with compatible systems.

Using It on the Job

1. Isolate Power: Before any work, ensure the main power to the ducted gas heating unit is turned off at the breaker and locked out.
2. Remove Old Thermostat: Carefully disconnect and remove the old wall controller, noting existing wire connections.
3. Mount New Thermostat: Secure the new Brivis thermostat to the wall in the desired location, ensuring it's level.
4. Wire Connections: Connect the 24V low-voltage wires according to the manufacturer's instructions. Usually, it's a few simple terminals for heat (W), fan (G), and common (C) if applicable, plus power (R).
5. Restore Power & Test: Re-establish power to the heating unit and test the thermostat's functions, checking for correct temperature sensing and heating activation.
6. User Orientation: Briefly explain operation to the client, emphasising its simplicity for heat control.

Limitations & Safety Notes

• This is a heat-only thermostat and will not control cooling functions.
• Designed specifically for 24V low-voltage systems; do not connect to line voltage.
• Always isolate power at the switchboard before beginning any installation or maintenance.
• Ensure wiring is correct and secure to prevent damage to the thermostat or heating system.
• Follow all relevant Australian electrical standards and Safe Work guidance during installation.

Tradie Pro Tip: When installing, make sure the thermostat isn't on an external wall or near a draught, as this can throw off temperature readings and lead to inefficient heating cycles. A good, central internal wall position is key for accurate room temperature sensing.
