Can't find the answer to your question in the manual? You may find the answer to your question in the FAQs about the Honeywell RTH230B below.

Where is the best location to place the thermostat?

The best place for the thermostat is the room where you spend the most time, in many cases the living room or kitchen. Place the thermostat about one and a half metres above the floor, not in the sun and not on an outside wall.

What is the dead band of a thermostat?

If your thermostat has a dead band, your installation is, as it were, 'at rest'. The thermostat only switches on when, for example, the difference deviates more than 2˚C from the set room temperature.

What is the ideal room temperature?

Most people find that the ideal room temperature is between 19 and 22 degrees Celsius.

Why is the display on my thermostat not turning on?

Make sure to check if the thermostat is securely connected to the power source and if the circuit breaker is not tripped. Additionally, verify that the batteries are properly installed and functional.

How can I adjust the temperature settings on my thermostat?

To adjust the temperature settings, press the up or down arrow buttons on your thermostat until the desired temperature is displayed.

Why is my thermostat not turning on the heating/cooling system?

Ensure that the thermostat is set to the desired mode (heat/cool), and the temperature is set higher/lower than the current room temperature accordingly. Also, check if the heating/cooling system's power switch is turned on and any relevant breakers or fuses are functioning correctly.

Can I program different temperature settings for different times of the day on my thermostat?

Unfortunately, this model does not have programmable features. You would need a different thermostat model with programmable capabilities to set different temperature schedules.

How can I change the battery on my thermostat?

At the bottom of your thermostat, locate the battery door. Open it, remove the old batteries, and insert new AA batteries, ensuring correct polarity. Close the battery door, and the thermostat should start functioning with the new batteries.
