Use the programmer's controls to set different temperature settings for specific times of the day and different days of the week. Refer to the manual for detailed instructions.

The room and cylinder thermostats use AA batteries. Open the battery compartment on the back of the unit and replace the batteries. Ensure correct polarity.

What is TPI control?

The wireless communication range is up to 30 meters in typical residential buildings.

Can I use this with any boiler?

The Honeywell Sundial RF2 Pack 3 is designed for traditional stored hot water systems. Check the compatibility information to ensure it suits your boiler setup. Professional installation might be required.

What if the wireless connection fails?

Troubleshooting

Check the programmer settings to ensure the heating or hot water is scheduled to be on. Verify the power supply to the programmer and check the batteries in the thermostats.
