Heating and cooling are the largest energy load in a guest room. A BLE Mesh thermostat puts per-room control on the same wireless network as the rest of the room, so the RCU can drive occupancy-based setback, scheduling and remote setpoint limits without touching the existing HVAC wiring.
What a BLE Mesh thermostat does
The thermostat reads room temperature, shows the setpoint on a local display, and reports to the in-room gateway. The RCU applies logic: comfort setpoint when occupied, setback when the card is removed or the room is vacant, and a freeze/heat floor when unoccupied for long periods.
Occupancy-based energy saving
- Card-power event: occupied = comfort, removed = setback.
- PIR timeout: no motion for N minutes implies vacant, nudges setpoint.
- Housekeeping override: a temporary comfort mode while cleaning.
- Seasonal limit: central cap on max cooling or min heating to stop abuse.
Retrofit advantage
In renovation projects the BLE Mesh thermostat replaces a wired stat with a battery or low-voltage wireless unit. No new conduit to the HVAC unit, no wall chasing - a key reason BLE Mesh suits old-hotel upgrades.
- Does a wireless thermostat need the HVAC rewired?
- No. The thermostat controls the existing fan coil, VRV or boiler valve through its normal control input. Only the stat-to-RCU link becomes wireless.
- How long do BLE Mesh thermostat batteries last?
- Typical alkaline or lithium cells last 1 to 2 years with normal polling, depending on display use and reporting interval.
- Can the front desk lock the setpoint?
- Yes. The RCU can enforce a central min and max so guests cannot set extreme temperatures that waste energy.
