Greenhouse Climate Controllers
Greenhouse climate controllers range from simple thermostats to multi-sensor climate computers that stage exhaust fans, circulation fans, pad pumps, vents and screens. ClimaSpan scopes controllers with your climate equipment so inputs and outputs match the house — without publishing catalogue model numbers or prices on this page.
Equipment selection and scope are confirmed in a written quote after we review your greenhouse size, layout, crop and climate. We do not publish public prices or catalogue-only spec sheets on these pages.
What controllers do
- Compare sensor readings to setpoints for temperature, humidity and related programmes.
- Stage or modulate fans, pad pumps, vents and screens when those actuators are connected.
- Provide alarms or manual override paths for operators and maintenance.
- Can sit beside irrigation automation when both are scoped for the same greenhouse.
Selection points
- List loops to control first: exhaust, circulation, pads, vents, screens, irrigation or alarms.
- Note existing sensors and whether you need a simple thermostat or a full climate computer.
- Share electrical supply and who will adjust setpoints day to day.
- Exact controller type and I/O are confirmed only in the written quote — no invented specs here.
How it pairs with structure and crops
- Sensor placement should reflect canopy height on benches or hydroponic rows.
- Exhaust and pad equipment need matching control signals and safeties.
- Screens and vents often share the same controller as fan stages.
- Crop programmes differ for leafy vs fruiting greenhouse crops — describe the crop when requesting a quote.

Frequently asked questions
Thermostat or climate computer?
Thermostats suit simple on/off staging. Climate computers suit multi-sensor programmes and several actuator groups. We recommend based on house complexity and labour — not a one-size list.
Can you control existing fans and pads?
Often yes if motors and valves accept the proposed signals. Send photos of nameplates and the current panel.
Do you list model numbers and prices here?
No. Controllers are quoted per project after we map sensors and outputs.
