Frequently asked questions

Common questions about PRO1 IAQ from 3G Electric.

What voltage do PRO1 IAQ thermostats operate on?

PRO1 IAQ low-voltage thermostats operate on 24V AC, which is standard for most residential and light commercial HVAC systems. This voltage is compatible with conventional furnaces, air conditioners, and heat pumps. Always verify the transformer capacity and wiring before installation.

What staging options are available on PRO1 IAQ thermostats?

PRO1 IAQ thermostats support staging from 1H/1C conventional up to 5H/3C heat pump configurations. For example, the T855 model offers 2H/2C conventional and 3H/2C heat pump staging, while the T855SH supports 2H/3C conventional and 5H/3C heat pump. Select the model based on your system's stage requirements.

Are PRO1 IAQ thermostats programmable?

Yes, several PRO1 IAQ models offer programming capabilities. The T805 features 7-day programming, and the T855SH offers 5-1-1 or 7-day scheduling. Manual models like the T501M and T625-2 use exposed dials or push buttons without programmable schedules. Check the product specifications for programming type.

What is the temperature differential on PRO1 IAQ analog thermostats?

The PRO1 IAQ T501M analog thermostat has a temperature differential of 1°F. This means the thermostat will activate heating or cooling when the room temperature deviates by 1°F from the set point, providing tight temperature control for comfort.

Can PRO1 IAQ thermostats be used with heat pumps?

Yes, many PRO1 IAQ thermostats support heat pump systems. Models like the T625-2 and T725 offer 2H/1C heat pump staging, while the T855 and T855SH support up to 3H/2C or 5H/3C heat pump configurations. Ensure the thermostat's terminal designations match your heat pump's wiring (e.g., B/C/O for reversing valve).

What wireless sensors does PRO1 IAQ offer?

PRO1 IAQ offers the R751WO wireless remote sensor, which detects motion and temperature for indoor use. It operates with the PROsync Wireless System, has a temperature range of 44° to 90°F, and mounts on surfaces. This sensor is suitable for zone-based temperature monitoring and occupancy detection in commercial or residential spaces.
