depending on specific pressure drop requirements

the compatible MKC-2 or OMKC-2 coil must be sourced separately for electrical actuation

the 20-707 is identical to the 10-53

preventing air binding and ensuring the pump operates within its designed duty cycle

007 orifice ensures that the air volume is restricted enough to allow the thermostat to maintain control over the branch pressure without overwhelming the system's air compressor capacity

Johnson Controls A19AAF-12 Temperature Control 30067439-890 depending on specific pressure dropThe Johnson Controls A19AAF 12 is a robust mechanical temperature control engineered for high performance heating and general purpose HVACR applications. Built with a single pole double throw (SPDT) switch configuration, this remote bulb controller delivers precise temperature regulation across a broad 25 to 225? F setpoint range. The unit features an automatic reset mechanism and a 3. 5? F fixed differential, ensuring consistent cycling and system
