12-Pack Programmable HVAC Thermostat

The PRO1 IAQ T705_v2 is a wall-mounted digital thermostat designed for single-stage heating and cooling systems. Each unit in the 12-pack provides 1H/1C control for residential or light commercial indoor climate management.

220-Volt Relay Contact Rating

The smart digital relay is rated specifically for 220-volt circuits, making voltage compatibility the decisive specification. Installers must verify the control circuit matches this rating before wiring the thermostat.

Steady-State Temperature Regulation

Under continuous operation, the programmable logic maintains the target setpoint by cycling the single-stage equipment without short-cycling. The thermostat delivers consistent comfort and energy savings over extended heating or cooling seasons.

Questions about this item

What does the 1H/1C rating mean once the T705_v2 is installed?

It controls one heating stage and one cooling stage, so the thermostat can call for heat or call for cool but cannot manage multi-stage equipment.

How does the 220 V relay contact limit what the thermostat can switch?

The internal relay is rated for 220 volts, so it can directly switch line-voltage heating or cooling loads up to that voltage without an external contactor.

What does the wall-mount kit include for fitting the T705_v2?

Each of the twelve units ships with its own mounting bracket and user manual for direct wall installation.
