York 145026 S1-025-41329-000 "SPST Temp Controller

CNTRL,TEMP,26 OPEN,38 CLOSE,SPST

The York 145026 S1-025 temperature control switch (part number CNTRL,TEMP,26 OPEN,38 CLOSE,SPST) is an inline temperature control switch used to provide manual control of heating and cooling equipment. The temperature control switch has SPDT (single pole double throw) contacts. The high level contact turns power on when the set point temperature has been reached. The low level contact turns power off when the set point temperature has been reached.

Includes pneumatic remote and manual control (CNTRL, TEMP), and is powered by 24VDC only.

The SPST temperature controller, along with other accessories are used to build robust digital temperature control circuits.

A single pole single throw temperature controller. A switch that when closed completes the circuit to power the device connected to it. A switch that when open breaks or interrupts the circuit connected to it. It is also called the "Micro Switch" because it has electrical contacts in much the same way as a larger, much more complex microprocessor controlled ballast does.

Simple to use easy to install Non-Programmable Digital room thermostat. Works with most standard heating, ventilation, and air conditioning systems using up to 24VAC/120VDC.

York Single Stage Temp Controller has a slim-line design that fits in the tightest spaces. Use with lead free refrigerant in cooling systems with air duct heat to tap control.

The York Digital Programmable Controller is a time-tested unit that provides precise control over water temperature during the HVAC make-up cycle. The controller can be used with wet or chilled water, and is compatible with any standard 24VDC thermostat.
