The IO HVAC CONTROLS iO-TS65_10 is a fixed-setpoint temporary heating thermostat packaged in a 10-unit pack, designed for construction-phase heating applications. Factory-set to 65 degrees F, this thermostat maintains a minimum ambient temperature in unoccupied structures without requiring manual adjustment. It is a low-voltage control device installed by HVAC technicians on temporary or permanent heating equipment during the construction phase of residential and light commercial buildings. The compact profile measures 5 inches wide by 8 inches tall by 0.25 inches deep, making it easy to mount in standard thermostat locations across multiple job sites.
This thermostat is suited for temporary heat setups during new construction, renovation, or winterization projects where a fixed heating setpoint is required by code or contract. The 10-pack quantity makes it practical for mechanical contractors managing multiple units or buildings simultaneously, reducing per-site procurement time. It is typically used with gas furnaces, electric air handlers, or other 24-volt heating systems commonly deployed for construction heat.
Designed as an OEM-style replacement and temporary-use thermostat compatible with standard 24-volt heating systems commonly used for construction heat applications.
Installation should be performed by a licensed HVAC technician in accordance with local mechanical codes and the equipment manufacturer's wiring specifications. Power down the heating system and confirm 24-volt control circuit is de-energized before making any thermostat wiring connections. Mount to a wall surface away from drafts, direct sunlight, and heat sources that could affect the fixed setpoint operation. After wiring, restore power and verify the heating system cycles on and holds the 65-degree setpoint correctly before leaving the site.
