Are you wondering why the Hive thermostat is off but heating on? Well, we’re here to assist you!
If the HVAC system keeps heating all connected radiator/heater appliances after disabling the thermostat, there could be an installation-related issue.
This guide will uncover all possible factors for the re-occurring heating problem and review some reliable troubleshooting solutions.
If the Hive system keeps heating even after turning off the thermostat, reset the power supply of all Hive devices and check the “Gravity” HVAC valve. Next, manually deactivate the boilers/radiators, and factory reset the Hive thermostat system.
Remain invested in uncovering all reliable resolution methods!
Why Does the Hive Heating Won’t Turn Off?
Typically, a simple issue with the Hive thermostat itself could also cause issues with the heating schedule and the temperature.
It is also possible that a clogged or broken gravity valve in the system is not functional and is actively preventing the natural convection process of the furnace.
Here’s why the Hive thermostat is off, but the heating continues:
The sole ability of the thermostat is to control the state of the anti-gravity and the check valve to control the heating correspondingly.
An unconventional switch could prevent the Hive Central Heating System from operating the temperatures properly and could cause heating anomalies.
Hive Thermostat Off But Heating On – Proven Ways to Fix!
Tip: Follow our instructions in a consecutive order!
1. Reset the Thermostat’s Power!
So, perhaps the Hive thermostat has failed to close the water circulation of the system due to temporal power supply issues.
An effective way to restore the thermostat’s functionality and all HVAC system features is simply by reinserting the battery units.
Here’s how to reset the power supply of the Hive thermostat in easy steps:
- Remove the Hive thermostat from the setup wall mount.
- Find the battery compartment and expose the batteries.
- Eject all four batteries from the thermostat’s compartment.
- Wait for 60 seconds while the thermostat is deactivated.
- Reinsert all four of the batteries back into your thermostat.
- Close the battery latch and reinstall the Hive thermostat.
It’s crucial to check the positioning of the battery compartment’s cover and verify that the four batteries are correctly installed.
The electrical poles of the batteries must be in contact with the springs/connectors, and if they are missing, bent, or defective, the device will not draw power.
Hive Thermostat Batteries?
If the heating won’t deactivate even after power cycling the Hive thermostat, the thermostat has encountered an error while attempting to operate the system.
Worn-out batteries primarily cause this issue, so insert a fresh set of four double-A or tripe-A batteries.
Note: The standard Hive thermostat uses double-A, while the mini uses tripe-A batteries.
2. Repair the Anti-Gravity Valve
A defective anti-gravity valve is one of the primary reasons the system’s heating lasts after deactivating the Hive thermostat.
The valve prevents unwanted circulation and is typically installed on the flow pipe from the HVAC boiler’s opening.
How to Identify the Anti-Gravity Valve?
Since multiple valves and switches exist in your HVAC compartment, identifying which valve is the anti-gravity valve in particular is necessary.
All anti-gravity valves have numbers on the upper ledge and are widened towards the conventional pipe of the boiler.
Spin the valve left/right to activate/deactivate the HVAC circulation.
How to Control/Repair Anti-Gravity Valve?
Hence, a defective anti-gravity valve will not prevent the circulation and heating of water, even after setting the Hive thermostat in your system to “OFF.”
Verify that the valve is secured by tightening the wrench nuts on either end and holding the pressure to prevent any circulation.
- The more loosened the anti-gravity valve, the stronger the circulation/heating of your system will be.
Generally, anti-gravity valves have to be adjusted manually and cannot be controlled solely through the functions of the thermostat in your HVAC system.
Note: Contact Hive if the anti-gravity valve seems defective and cannot be repaired!
3. Set the Boiler Valve to “OFF”
If the thermostat is seemingly off, but the system is still heating your radiators, the boiler could have an issue.
If you’ve manually configured the boiler’s control valve, the HVAC system could be heating independently of the Hive thermostat device.
The Hive thermostat can typically work with any boiler in your HVAC system!
Here’s how to check the control valve of the HVAC boiler:
- Access the boiler/furnace room and find the central boiler.
- Examine all walls of the boiler and locate the control valve.
- Spin the valve towards the “COOL” icon to prevent heating.
- Deactivate the water flow of the boiler to stop circulation.
- Check if the HVAC system is still heating the circulating water.
If you’re using an older boiler that doesn’t have a regulation valve, simply disconnect the appliance from power.
This should prevent the circulation water in the HVAC system from getting any warmer until the issue with the Hive installation is identified.
Alert: Seek qualified assistance from a technician if the boiler’s valve is damaged or clogged!
4. Unplug the Hive Receiver Temporarily!
If the Hive heating won’t turn off, disconnecting the Hive receiver from power is another effective resolution.
The receiver acts as a meeting point for all units in the Hive Central Heating system, so unplugging it should deactivate the heating of all connected radiators.
Follow these steps to power off the Hive receiver in easy steps:
- Hold the “Action” button on the centre of the Hive receiver.
- Keep holding the button for 10 seconds to power off the Hive.
- Stop holding the action button once the display goes blank.
Note: Check if the heating will deactivate automatically after turning off the receiver!
5. Deactivate All HVAC Heaters/Radiators
Modern radiators typically have a control switch that prevents the water inside the appliance from heating up via the pipes.
So, if the heaters or radiators in your HVAC system work independently from your thermostat, you might have to deactivate the devices manually.
HVAC Radiator Has a Control Switch?
The control switch should typically be located above the HVAC pipe on the radiator.
Turn it towards the “OFF” side to deactivate the device’s heating or check if a float switch prevents HVAC-controlled water from entering the appliance.
How to Prevent Radiator Water Flow?
A standard HVAC instalment uses circulating water heated by boilers to heat your home.
Therefore, cutting the water supply to the radiator should effectively prevent the heating process, so check if an in-built pipe valve blocks the circulating water.
Remember that the water should not stay in the pipe for too long.
After deactivating the circulation to the connected radiator, withdraw all the water from the system in the HVAC compartment.
Note: If you wish to reactivate the heating, restore the water circulation to all radiators!
6. Restore the Thermostat to Factory Defaults!
It is advised to erase all system configurations by performing a factory reset to address all lasting issues with the Hive thermostat.
This process will effectively resolve underlying issues with the settings and the hardware of the thermostat’s heating capabilities.
The device must be up and running to factory reset the Hive thermostat!
Here’s how to perform a factory reset on the Hive thermostat in easy steps:
- Verify that the Hive thermostat is idling on the home screen.
- Hold the “Back” arrow and the “Menu” buttons simultaneously.
- Wait for the factory reset cooldown to appear on the screen.
- After 10 seconds, the Hive thermostat should power off by itself.
Once the Hive thermostat has powered off, the factory reset has started.
Do not interact with the thermostat, disconnect it from the wall mount or remove the batteries for the next 2-3 minutes, or you may accidentally cancel the factory reset process.
Note: The Hive thermostat will reboot once the reset is complete!
Need More Help?
