Frequently Asked Questions - OR80 OT BOSCH
How do I install the Bosch OR80 OT thermostat?
Follow the installation guide: turn off power to your HVAC system, remove the old thermostat, label wires, connect them to the matching terminals on the OR80 OT, mount the base, and attach the faceplate. Insert batteries before mounting.
How do I set the temperature schedule?
Press the Menu button, navigate to Schedule, and set your desired temperature for each time period (Morning, Day, Evening, Night) for each day of the week. Confirm with OK.
Why is my thermostat displaying 'Lo' or 'Hi'?
'Lo' indicates the temperature is below 5°C, 'Hi' indicates above 35°C. This may happen if the sensor is faulty or the thermostat is near a heat source or draft. Check placement and ensure proper ventilation.
How do I reset the thermostat to factory settings?
Press and hold the Menu button for 10 seconds until the screen resets, or remove the batteries, wait 30 seconds, and reinsert them. This clears all custom schedules.
What type of batteries does the OR80 OT use?
It uses 2 AA alkaline batteries (1.5V each, 3V total). Replace them annually or when the low battery indicator appears.
Can I use the thermostat with a heat pump?
Yes, the OR80 OT is compatible with heat pumps. Set the system type in the configuration menu to Heat Pump to enable auxiliary heat control.
How do I adjust the temperature offset?
Go to Settings > Calibration. Adjust the offset by ±3°C using the up/down arrows. This compensates for thermostat placement.
What does the 'Key Lock' feature do?
The Key Lock prevents accidental changes. Press and hold the Up and Down buttons simultaneously for 3 seconds to lock or unlock the screen.
How often should I clean the thermostat?
Clean the exterior with a soft dry cloth every few months. Avoid using liquids or abrasive cleaners, as they may damage the display.
