The O/B reversing valve is a crucial component of heat pump systems that switches the operation between heating and cooling. Depending on how your HVAC system is wired, the valve may need to stay energized or de-energized when the system is idle.
With the Cielo Smart Thermostat Eco, you can customize this setting to match your system’s requirements, ensuring smooth operation and efficient temperature control.
Configuring O/B reversing valve in Cielo Smart Thermostat Eco
Step 1: On the Control Screen, tap on the ‘Settings’ icon at the top right corner.
Step 2: Tap on 'HVAC Settings'.
Step 3: Tap on ‘HVAC system’, then ‘Heat Pump Preferences.’
Step 4: You can choose whether the O/B reversing valve in the idle state should remain ‘Same’ or ‘Off’. This depends on whether you want the O/B valve to stay energized until the opposite of heating or cooling is called or to be left unenergized whenever there is no heating or cooling. (Tap on the tooltip to learn about these settings.)
Tap on ‘Apply.’
