- Figure 2 shows a connection to an electric SCR reheat coil that is proportionally controlled. You can use the same heating percent command signal, which is 0 V to 10 V, to control either an SCR reheat coil, or a proportional water valve, depending on what is present.
- Supplemental valves use to the 60-second incremental actuator factory default value. You can adjust this in Verasys.
- You can average up to five NS sensors. Connect the NS sensors in a daisy-chain configuration using the addresses in the Configuring the NS sensors section. The fifth sensor must have the fixed address 199.
- If you install CO2 Net sensors, in addition to the 24 VAC power for the controller, you must also supply 24 VAC power the HOT and COM terminals.
