FAQs

How do I set a schedule?

Navigate to the scheduling menu on the thermostat and follow the prompts to set your desired temperatures and times for each day of the week.

How do I use Holiday mode?

Go to the Holiday mode settings and set the desired temperature and the number of days you'll be away. The thermostat will then maintain that temperature until the end date.

What if the display is blank?

Check the power supply to the thermostat. Verify that the unit is properly wired and receiving power.

Can I manually override the temperature?

Yes, use the up and down arrow buttons to adjust the setpoint. You can choose to hold the new setpoint until the next programmed time, or for a set period.

Is the T4 compatible with my boiler?

The T4 is designed for on/off heating systems, so it is compatible with most standard boilers. Always check the boiler's manual to confirm compatibility before installation.

Where can I find the user manual?

The user manual is included in the product packaging. You can also download it from the Honeywell website by searching for 'Honeywell T4 Wired Room Thermostat'.
