Johnson Controls C-2220 High-Low Pressure Selector
The C-2220 High-Low Pressure Selector selects and transmits control pressure signals from a group of thermostats or controllers. The selector is available in either high or low volume output modules. The appropriate C-2220 module must be selected to work with either high or low volume thermostats or controllers. The C-2220 High-Low Pressure Selector can be combined in master and slave module groups for applications using both high and low volume output thermostats or controllers. Refer to C-2220 High-Low Pressure Selector Product Bulletin (LIT-7171420) for important product information.
