Description
The Johnson Controls A70HA-1C Temperature Controller is a controller that is used to control the temperature in HVAC systems. It mostly operates as a low-limit controller, to prevent temperatures from going down to a certain level that is dangerous to the equipment or poses a problem to the operation. This controller comes with a 4-wire 2-circuit and can be reset manually. It has a universal voltage Compensation feature that works on anything from 120VAC to 600VAC in HVAC systems. The temperature ranges from 15°F to 55°F which makes it flexible in heating and cooling. Essential to its operation is a 20-foot capillary tube which senses temperature variations and the ability to switch between its functional modes manually.
