Intronics Digital Room Thermostat User Guide Here
In "Off" mode, the thermostat usually retains a frost protection setting. It will not allow the room to drop below 5°C (41°F). Do not manually override this by disconnecting power if the building is unoccupied during winter.
This is where Intronics pays for itself. You will program "Comfort" temperatures (when you are home) and "Setback" temperatures (when you are asleep or away).
Most Intronics thermostats support 6 time zones per day (sometimes 4). Here is the standard 4-zone setup:
| Zone | Time | Target Temp | Activity | | :--- | :--- | :--- | :--- | | Wake Up | 06:30 | 21°C (70°F) | Morning comfort | | Away | 08:30 | 16°C (61°F) | Energy saving (work hours) | | Evening | 17:00 | 22°C (72°F) | Back home, relaxing | | Night | 22:30 | 15°C (59°F) | Sleep / Frost protect |
| Code | Function | Recommended Setting | | :--- | :--- | :--- | | F1 | Temperature Calibration (±3°C) | If your thermostat reads 20°C but a separate thermometer says 19°C, set this to +1. | | F2 | Switching Differential (Hysteresis) | 0.5°C for boilers; 1.0°C for electric floor heating (to prevent rapid clicking). | | F3 | Frost Protection Temp | 7°C (Default – stops pipes freezing). | | F4 | Sensor Type | In (Internal only) / Out (Floor sensor only) / AL (Both – for underfloor). | | F5 | Max Floor Temp Limit | 27°C for tile; 35°C for wood (Only if using floor sensor). | | F6 | Restore Factory Settings | Select "RST" and confirm. | intronics digital room thermostat user guide
