Johnson Controls S350A Series Temperature Stage Module

Temperature Stage Module
S350A Series

The S350 Stage Module is used in conjunction with the A350, A350E, A350P, and A350R series temperature controls to add multiple stage capability. The S350 module has an SPDT output relay and three adjustments including offset (de-energize stage action from setpoint), heating or cooling mode, and differential. Using a Y350R, up to nine S350As can be added to the A350, A350E, and A350R via the 5-pin, plug-together connector. Using a Y350R with an A350P, up to four S350As can be added. Using a 40 VA or greater external transformer with an A350P, up to nine S350As can be added.

 

 

• heating or cooling mode, field-selectable jumper
• adjustable differential and offset
• 5-pin connector eliminates wiring between modules
