3.CONTROLS AND REMOTE COMMUNICATION (OPTIONAL)

A.DIGITAL CONTROL OPERATION

(1)Figure 11 shows the components of the NORTEC Controller and how to adjust the setpoint.

(2)In the case of a modulating NORTEC Controller, Figure 12 shows the relation between the difference from setpoint to %rh in the room and the 0-10 V DC demand signal sent out. From this basis the NORTEC Controller uses its PI algorithm to adjust its demand signal in accordance with the history of the environment. This type of control allows for tighter and more precise control.

B.DIGITAL TRANSDUCER OPERATION

(1)The NORTEC digital transducers, shown in Figure 13, are designed to sense humidity in duct or in room respectively, and report it back to a controller or the NHTC directly. Required humidifier output is determined by controller or humidifier.

C.REMOTE CONNECTIONS (OPTIONAL)

CAUTION

NORTEC DOES NOT RECOMMEND USING THE DRY RELAY

CONTACTS WITH ANYTHING MORE THAN 24 VAC, 1 AMP.

(1)The NHTC reports the signal light status, in Table 3, by closing the supplied dry contact relays which can be wired back to a BMS or monitoring station. This method of monitoring is not as informative as the actual display, but alerts you to the general status of the unit.
