FrostLine can operate locally from the thermostat or remotely through a VolticHub or a Tuya-compatible Zigbee Hub. The interface, menu names, and available features may vary by Hub and firmware.

Initial setup

1

Check the wiring and power the device

Verify that the diagram matches your installation and that protections are in place. Power-up must be performed by a qualified electrician.
2

Pair FrostLine with the selected Hub

Add the device from the Voltic platform or Tuya Smart / Smart Life, depending on the installed Hub. Follow that Hub’s inclusion procedure.
3

Select the HVAC scenario

Configure the installation type (2-pipe, 4-pipe, or fan coil with underfloor heating) only if it is available for your version and matches the validated diagram.
4

Set the temperature and fan control

Set heating or cooling, the temperature setpoint, and fan speed. For 4-pipe or combined installations, also check each circuit’s priorities.
5

Test each output

Test the valve, V1/V2/V3 fan speeds, and, where present, the underfloor actuator separately. Do not approve the installation just because the display turns on.

Scenario behavior

The actual sequence depends on the approved diagram; check the compatibility matrix before changing it.

Daily use

  • Change the setpoint from the thermostat or the Hub app.
  • Select heating or cooling according to the season and installation configuration.
  • Adjust fan speed when supported by your model.
  • Use schedules or Hub automations when they are available for your model.
  • Allow the measured temperature to stabilize before changing several setpoints in succession.

If something does not work

  1. Check that FrostLine appears connected on the selected platform.
  2. Verify that the Hub is online and the device is not paired to another account.
  3. Review terminal mapping and each load’s voltage without energizing the circuit during inspection.
  4. Test one output at a time and record the result.
  5. Contact Voltic support with the device reference, firmware, Hub, and installation diagram.
