In a hotel, Voltic FrostLine does not operate in isolation: it receives the Room Control setpoint and works with the VolticHub, presence sensors, and window sensors.

​
What FrostLine controls

  • The room temperature setpoint.
  • The HVAC mode configured for the project.
  • The fan coil valve or valves according to the approved diagram.
  • Fan speeds V1, V2, and V3.
In a 4-pipe or fan coil plus hydronic underfloor-heating installation, the cooling, heating, and priority sequence is defined by the project. Do not change that configuration from a room without validating the diagram with maintenance or support.

​
Behavior by room state

The table describes Room Control behavior; see ECO and COMFORT modes to change timers and setpoints centrally.

​
Hotel operating flow

1

Configure global behavior

Define ECO and COMFORT setpoints and presence and window timers from the Control Panel.
2

Monitor rooms

In app.voltic.es, verify that FrostLine is connected, reports temperature, and belongs to the correct room.
3

Respond to an incident

Identify whether the problem affects the Zigbee network, a sensor, the platform, or a fan coil output before touching wiring.
4

Validate the repair

Test a setpoint, the valve, all three fan speeds, and the window and presence responses before returning the room to operation.

​
Quick checks

Do not open or rewire an energized FrostLine. Electrical checks must be performed by a qualified electrician with the circuit isolated and verified.

​
Maintenance and room changes

Before replacing a FrostLine or moving a kit:
  1. Record the room, device reference, and firmware.
  2. Unpair and include the device again following the VolticHub procedure.
  3. Verify that the room association and automations are preserved.
  4. Run the complete room validation before making the room available again.
Do not swap kits between rooms: each kit is preconfigured for a specific room.
