You may want to check out our webinar on using the Puck Pro as an integrated control.
To qualify for rebates, Puck Pros must be installed professionally. The following requirements are for the Flair secondary heat feature:
- A Pro Edition Puck for each mini split head unit. These are available via supply houses and distributors listed on flair.co/integrated-controls.
- A smart thermostat must be integrated in the Flair App. The list of compatible smart thermostats is available at flair.co/integrated-controls
- At least one mini split heat pump configured on the Flair App that is capable of heating.
Configure Flair App Settings
The following Flair settings are required for Secondary Heat
Set Point Controller
- Tap the Flair Menu
- Then go to Home Settings->System Settings
- Set "Set Point Controller" to "Flair App"
- Tap the Flair Menu
- Then go to Home Settings->Away Settings
- Set "Away Mode" to "Smart Away"
- Select Smart Away bounds (Minimum room temperature when heating and Maximum room temperature when cooling)
In the Control Bar, set "Mode" to "Heat":
Each room with a mini split must belong to two zones: the thermostat's zone and the mini split's zone.
For each room with a mini split do the following:
- Tap the room
- Tap the 3-dot menu on the room tile
- Then go to Settings->Room Info
- Check the mini split's zone box and the thermostat's zone box
Configure Second Stage Heat Settings
After completing Flair Setup, configure Secondary Heat settings.
- Navigate to Secondary Heat Settings
- Select Secondary Heat Option
- Set Balance Point
- Set Primary Heat Cutoff Delay
Navigate to Secondary Heat Settings
- Tap the Flair Menu
- Then go to Home Settings->Thermostats
- Tap the down arrow to expand the thermostat
- Tap Use as "Secondary Heat Setting"
- If you don't see "Secondary Heat Setting", check Required Flair App Settings
Select Secondary Heat Option
- Disabled: Flair will not provide staged heating
- Supplemental Heat: Flair will run primary heat and turn on secondary heat at the enable temperature and turn off secondary heat at the disable temperature
- Cutover: Flair will run primary heat and switch to secondary heat at the cutover temperature and switch back to primary heat at the cutback temperature
Set Balance Point
- Set the "Cutover Temperature" or the "Enable Supplemental Heat Temperature" to the balance point for the mini split.
- Set the "Cutback Temperature" or the "Disable Supplemental Heat Temperature" 5F higher.
Set Primary Heat Cutoff Delay
When using "Cutover", this setting allows the mini splits to continue to run for a period of time while the secondary heat source warms up. Values range from zero to twenty minutes. A value of zero means that mini splits will turn off immediately when cutting over to the secondary heat source. A value greater than zero means that mini splits will continue to run for that amount of time after switching over to the secondary heat source.
- Important Considerations
- Prior to Testing
- Testing Cutover/Add Supplemental Heat
- Testing Cutback
- After Testing
To test secondary heat, you'll adjust the set point and the secondary heat settings in relation to the current outside temperature. Once testing is completed, you can change the settings back to their appropriate efficiency values.
- Flair may take up to 5 minutes to relay commands to mini splits and smart thermostats
- It’s recommended to perform tests at least 15 minutes apart to allow time for primary and secondary heat systems to warm up and cool down
- Keep in mind, that If the room is already up to temperature, heat sources may not come on right away
Prior to Testing
Follow the steps below to create an initial state for testing. If you encounter any unexpected behavior, return to this state and restart testing.
- Set the smart thermostat to OFF
- Turn ON the mini splits using their respective remote controls. Then place the remotes permanently in a drawer or room where their signals can’t interfere with Flair
- In the Flair app Control Bar, tap the thermometer and use the slider to adjust the “Home Set Point” 5F higher than the current room temperature - it may need to be higher to get mini splits to cycle on
- Wait the for mini splits to cycle on before proceeding
Testing Cutover/Add Supplemental Heat
- In the Flair app, tap the Flair menu, then go to Home Settings->Thermostats and expand the thermostat
- Adjust the “Cutover Temperature” or the “Enable Supplemental Heat Temperature” so it’s 3F above the current outside temperature (Flair displays outside temperature in the control bar)
- Then change the “Cutback Temperature” or the “Disable Supplemental Heat Temperature” to 5F above the "Cutover Temperature" or the "Enable Supplemental Heat Temperature", respectively
- This will prompt Flair to send an ON command to the smart thermostat. the system to warm up and come on. If Cutover is enabled, Flair will send an OFF command to the mini splits. Allow time for Flair to send the commands (up to 5 minutes). Allow mini splits time to cycle off. You may need to set the home set point higher for the secondary heat system to come on.
- Adjust the “Cutover Temperature” or the “Enable Supplemental Heat Temperature” so it’s 3F below the current outside temperature.
- This will prompt Flair to send an OFF command to the smart thermostat. If Cutover is enabled, Flair will send an ON command to the mini splits. Again, allow time for Flair to send the commands and for the systems to adjust to being turned off and on.
When you've verified secondary heat functionality, set the set point and secondary heat settings to their appropriate efficiency values.
If you experience unexpected results during testing, disable the “Use as Secondary Heat” setting and wait 15 minutes. Then re-enable the “Use as Secondary Heat” setting and return to the "Prior to Testing" section to create the initial state and run through tests again.
Note: if the room is up to temperature, the primary and secondary heat sources may not come on right away. Adjust the home set point higher.
