Honeywell RTH7500 Series Programmable Thermostat

Safty Instruction

Removing your old thermostat

• Turn power OFF. To protect yourself and your equipment, turn off the power at the breaker box or switch that controls your heating/cooling system.
• Check that your system is off. Change the temperature on your old thermostat. If you don’t hear the system turn on within 5 minutes, the power is off.
•  Remove the old thermostat’s faceplate. On most thermostats, you can take off the faceplate by grasping and gently pulling. Some thermostats may have screws, buttons, or clasps. Do not remove any wires from your thermostat at this time!

Make sure there are no 120 V/240 V wires.

FAQs

Q: How do I install the Honeywell RTH7500 thermostat?

Before you begin, turn off the electricity to your heating and cooling system at the breaker. After removing your previous thermostat, connect the wires to the appropriate terminals on the RTH7500 base and label them with the terminal letters. After that, reattach the faceplate and turn on the power.

Q: Does the RTH7500 work with all HVAC systems?

The majority of 24-volt heating and cooling systems, such as central air conditioners, gas, oil, and electric furnaces, and heat pumps (with or without auxiliary heat), are compatible with the RTH7500.
It is incompatible with 120/240V electric baseboard heating systems and millivolt systems, such as floor furnaces.

Q: How do I program the thermostat?

Set temperature schedules for the Wake, Leave, Return, and Sleep times after selecting the day and time by pressing the “Set” button. For every day of the week, you can program up to four time slots.

Q: Can I use the thermostat without programming it?

Indeed. By setting a manual temperature and selecting “Hold,” you can prevent automated schedules from starting until you decide to resume them.

Q: How do I change between heating and cooling modes?

To switch between the available modes—Heat, Cool, Auto, and Off—press the System button. The thermostat automatically alternates between heating and cooling while it is in Auto mode.

Q: How do I set different programs for weekdays and weekends?

You can select one schedule for Monday through Friday and another for Saturday through Sunday because the RTH7500 supports 5-2 day programming.
