IO Hvac Controls iO-TS75 Thermostat
The iO-TS75 Temp-Stat is a rugged, non-adjustable temporary construction thermostat engineered specifically for heating applications. Preset at a fixed 75-degree setpoint, this 24V low-voltage control prevents energy waste by eliminating the ability for unauthorized personnel to tamper with temperature settings during the rough-in or finishing phases. Its conductive bimetal construction features gold-diffused contacts, ensuring low internal resistance and reliable switching performance in demanding environments. Designed to withstand the rigors of a job site, the iO-TS75 is metal encapsulated and protected by a durable PVC outer jacket, shielding the internal components from drywall dust, paint overspread, and moisture.
For high-performance system protection, this unit incorporates an internal capacitor to absorb the electrical arc when contacts open and close. This suppression prevents heat buildup within the housing, effectively mitigating equipment short cycling and extending the life of the furnace or air handler. The iO-TS75 features pre-stripped 20 AWG stranded leads rated at 600V, allowing for rapid integration into any standard 24VAC HVAC control circuit using the R and W terminals. Whether you are managing a multi-family project or a commercial build, this creep-action thermostat ensures consistent 75-degree heating without the risk of theft or damage common with expensive digital interfaces.
Key Benefits for Contractors
- Fixed 75-degree heating setpoint eliminates energy theft and prevents site trades from overheating the structure.
- Gold-diffused bimetal contacts provide superior conductivity and long-term switching reliability for 24V control circuits.
- Arc-suppression capacitor prevents internal heat generation to ensure an accurate 1.5-degree temperature differential.
- Durable PVC-jacketed encapsulation protects the sensor from plaster, spackle, and job site contaminants.
- Universal compatibility with low-voltage heating systems, including gas furnaces, electric heat, and heat pumps via the auxiliary heat terminal.
Common Questions
How do I wire the iO-TS75 for a standard heating system?
Installation is straightforward; simply connect the iO-TS75 across the R (Power) and W (Heat) terminals on the equipment control board or transformer circuit.
Can the iO-TS75 be used with a 120V or 240V line voltage heater?
No, this is a low-voltage 24VAC device rated for a maximum of 1.0 Amp. For line voltage applications, you must use a specialized isolation relay kit such as the CS-RY-115 or CS-RY-220.
Will the iO-TS75 work with a heat pump system?
Yes. To operate the resistance heat during construction, wire the unit to the R and W terminals. If you intend to run the compressor for heat, wire it to R and Y, ensuring the reversing valve is in the correct default position for the equipment.
