The controller is designed for industrial applications. Do not use in environments with explosive gases or excessive vibration. 3. Installation and Mounting

Press the key to initiate. The controller will intentionally oscillate the output a few times to measure system lag and thermal inertia.

A: Yes. Set oH (Output 1 action) to 0 (Reverse action for heating) and oC (Output 2 action) to 1 (Direct action for cooling). Or leave output 2 unused. Insert the controller into the panel and secure
