Relay output

Six relays can be programmed for heating, cooling, or fan operation. Operational voltage level by

dual-in-line switches.

Mixed air sensor (optional)

The controller can provide a separate mixed air control, or limit control in conjunction with

proportional cooling output ramp.

Cold start On power failure.

Control output voltage Refer to the Description Model Chart and Proportional Outputs and Output Relays Model Chart.
