Functions
- Set-point Adjustment – The set-point buttons allows users to adjust the set-point (in 0.5 °C increments) for the space.
- Fan Speed – Users can select fan speed (High, Medium, Low and Automatic) by pressing the Power/Fan button.
- Mode Control – Users can switch operating modes (Heating, Cooling, or Ventilation) by pressing the Mode button.
- Eco Saving Mode – Pressing the Eco button starts the energy savings mode. In cooling mode, the set-point is automatically adjusted to 26 °C and the fan speed is set to Low. In heating mode, the set-point is automatically adjusted to 18 °C and the fan speed is set to Low. The user can exit the energy saving by pressing the Eco button.
- Button Lockout Function – Allows the buttons to be deactivated to prevent thermostat operation by others.
- Low-Temperature Protection – If the room temperature drops below 5 °C, the thermostat will start automatically and the fan speed will be set to High. Once the temperature reaches 7 °C, the thermostat will switch off the output.
- Alert – In the event of an operating exception, the thermostat will attempt to command the valve to close and place the device in an inoperative state. The display will indicate the current status with one of four diagnostic messages.
Accessories
Remote Control
The IR-300 remote controller is suitable for TC300 series thermostats (deluxe models only). Control operations include Temperature Setpoint Adjustment, Fan Speed Selection, Mode of Operation, ON/OFF, etc. Requires two AAA batteries (not supplied).
Remote Sensor
The RS-03 remote sensor can be used in place of the existing built-in temperature sensor of the TC300 series thermostats (deluxe models only). It has the same 10 kΩ NTC (3950) element encapsulated in a plastic bulb housing that measures approximately Ø6 x 25 mm and is supplied with 3 m cable (2-wire), finished in all white. The RS-03 sensors are only available in multi-packs of 10 pieces.
