PECO TF115P Manual Dial Thermostat for Greenhouse Exhaust Fans
The PECO TF115P-002 Manual Dial Thermostat gives you simple, reliable temperature control for your greenhouse exhaust fan, intake vent, or heater. Set your target temperature with the dial — the thermostat does the rest, automatically switching your cooling or heating device on and off to maintain the right growing environment.
Key Features
- Simple dial control: Set your desired temperature directly on the dial — no programming or digital interface required
- Plug-and-play setup: Plug into any standard 110/120V outlet, then plug your exhaust fan or intake vent into the piggyback cord — no wiring needed
- Pre-configured for cooling: Ships ready to control exhaust fans and intake vents; includes a wiring diagram to reconfigure for use with a heater
- Weather-resistant enclosure: Rugged housing designed to withstand the humid, temperature-variable conditions inside a greenhouse
- Versatile compatibility: Works with any 110/120V exhaust fan, intake vent, or heater that plugs into a standard outlet
How It Works
Plug the thermostat into a 110/120V power source. Plug your exhaust fan or intake vent into the thermostat's piggyback outlet. Set the dial to your target temperature. When the greenhouse reaches that temperature, the thermostat automatically powers on your fan to cool it down — and shuts it off once the temperature drops back to the set point.
Cooling & Heating Use
The TF115P-002 is pre-wired for cooling mode (powers on when temperature rises above the set point). It includes a wiring diagram to reconfigure it for heating mode (powers on when temperature drops below the set point), making it a flexible year-round solution.
Compatibility
Compatible with any 110/120V plug-in exhaust fan, intake shutter vent, or heater. Pairs directly with Riga greenhouse exhaust fans (16", 20") and intake shutter vents (16", 20", 24") for a complete automatic ventilation system.

Frequently Asked Questions
What devices can I control with this thermostat?
Any 110/120V plug-in device — including exhaust fans, intake shutter vents, and heaters. It pairs directly with Riga greenhouse exhaust fans and intake vents for a complete automatic ventilation system.
Does it require any wiring or an electrician?
No. The plug-in piggyback setup requires no hardwiring. Plug the thermostat into a standard 110/120V outlet and plug your fan or vent into the thermostat's outlet — that's it.
Is it pre-configured for cooling or heating?
It ships pre-configured for cooling — it powers on your fan when the temperature rises above the set point. It includes a wiring diagram to reconfigure it for heating mode if needed.
Can I use this with a Riga greenhouse exhaust fan?
Yes. This thermostat is compatible with Riga 16" and 20" exhaust fans and all Riga intake shutter vents (16", 20", 24"). Together they form a complete automatic greenhouse ventilation system.
Is the enclosure suitable for greenhouse humidity?
Yes. The PECO TF115P features a weather-resistant enclosure designed to handle the high humidity and temperature swings typical inside a greenhouse.
What is the difference between this and a digital thermostat?
This is a manual dial thermostat — straightforward to set with no programming required. A digital thermostat offers more precise temperature settings and may include additional features like timers or displays, but the TF115P is the simpler, more affordable option for growers who want reliable automatic control without complexity.
