Environmental Controls & Thermostats J&D Manufacturing has the control for you! We offer a full range of controls, including Phason and Honeywell, that can operate everything from a single fan all the way up to controls that can monitor and regulate your entire environmental system. All of our controls are fully compatible with our extensive line of fans, inlets, lighting and cooling products.

VC115 & VC115-C Single Stage Thermostat The VC115 Single Stage Moisture Proof Thermostat is intended for applications that need a rugged, weather-proof control.		VC109 Two Stage Moisture Proof Thermostat The VC109 Two Stage Moisture Proof Thermostat is intended for applications that need a rugged, weather-proof control.
VC141 Single Stage Digital Thermostat Our VC141 Thermostat with digital display and remote sensor is ideal for controlling exhaust fans, recirculation fans, inlets, cooling devices and heaters.		VC241 Two Stage Digital Thermostat Our VC241 Thermostat with digital display and remote sensor can be used for two stages of cooling, two stages of heating, or one stage cooling plus one stage heating. It can also operate two speed fan motors.
PFABT775B Digital 4 Stage Control The versatile PFABT775B 4 stage Honeywell control can be used as a single or dual sensor control with a digital read out. You can run up to four heating stages, four cooling stages, or a combination of heating and cooling.		MSC4 & MSC4-C Manual Speed Control The MSC4 series control is a high amp capacity, dual voltage, manual variable control that is compatible with PSC variable motors, light dimming or heat lamps.
MTC4C & MTC4C-C Modulating Temp Control The MTC4C series allows you to automatically control ventilation fans according to the ambient temperature. It modulates the speed of a variable speed fan by increasing the fan speed when the temperature rises, and decreasing the fan speed when the temperature drops.		SUPRA 16 Stage PC Compatible Control The Supra automatically monitors and controls the temperature in up to four separate zones by operating ventilation equipment such as fans, heaters, inlet actuators, or curtain machines.
SupraSaver & SupraSaver-P The SupraSaver allows you to store your complete SUPRA control configuration and settings, and even transfer to other SUPRA controls or setup up a new SUPRA in seconds. The SupraSaver-P is programmed at our factory according to your settings.		ECC-1 Digital Evaporative Cooling Control The ECC-1 has six relays and is designed to automatically control sprinkler solenoids, water pumps, and fans for direct or indirect evaporative cooling systems.
NVC Natural Ventilation Control The J&D Natural Ventilation Control (NVC) is designed to effectively operate a curtain machine.		SPC Static Pressure Control The J&D Static Pressure Control (SPC) is designed to electronically monitor the static pressure differential in a room and effectively operate an inlet actuator by providing commands when to open or close.
OMNI-4000 Production Control System The OMNI-4000 is a personal computer-based system of hardware devices and software programs that allows you to have up to 256 hardware devices on a single system.		PLC-1 Programmable Lighting Control The PLC-1 Programmable Lighting Control has multiple outputs and programs which allow you to easily control light duration and intensity. It can control up to 4 separate lighting programs.
PLC-2 Programmable Lighting Control The PLC-2 Programmable Lighting Control has multiple outputs and programs which allow you to easily control light duration and intensity. It can control up to 3 separate lighting programs.		TVS Three Stage Ventilation Control J&D's Three Stage Ventilation Control (TVS) automatically controls the temperature in a room by operating two variable speed fans and a single speed fan or heater.
AEC2 Automatic Environmental Control The AEC2 is a three-stage control that automatically controls the temperature in a room by operating a variable speed fan and up to two single-speed fans or heaters.		VTC1D Variable Speed Temperature Control The VTC1D automatically controls temperatures by varying ventilation fan speeds.
FHC1D Variable Speed Fan & Heater Temp Control The FHC1D automatically controls temperatures by varying the speed of ventilation fans and controlling heating systems.		SECHD Staged Environmental Control The SECHD automatically controls the temperature in a room by operating two variable speed fans and up to three single-speed fans or heaters.
SECHD Plus Staged Environmental Control The SECHDPlus offers the same basic design as our SECHD, but for a smaller building.		PEC Proportional Environmental Control The Proportional Environment Control (PEC) automatically controls the temperature in a room by operating two variable speed fans, an inlet actuator, and up to three single-speed fans or heaters.
PEC Plus Proportional Environmental Control The PEC Plus controls the temperature by operating ventilation equipment such as fans, heaters, inlet actuators, curtain machines, or other equipment according to your programmed settings.		PFISC & PFISC-R Switching Centers The new J&D Manufacturing PFISC and PFISC-R switching centers have enlarged cases for easier wiring, and can be wired for 115 or 230 volt applications. Order with or without a relay.
