Start-up checklist

Your humidification system may not have all of the options listed

below. If an item does not apply to your system, skip to the next

item and continue the process.

☐ Before you start, read this manual and other information sent

with your humidifier.

☐

Verify that the field wiring is done per the instructions in this

manual and per the unit wiring diagram.

☐

If your humidifier uses potable or softened water (non-DI

water), check probe voltages in the Diagnostics menu. The

reading should be 2.3 VAC without water and 0 VAC with water

from ground (terminal 33 on J8) to probe inputs (terminals 30,

31, and 32 on J8).

☐

Check the heater cycle time setting (except for GTS) in the

“System Set Up” menu of the keypad/display (default is 60

seconds; 2 seconds for SSR).

☐

If your system uses an RH transmitter, check the proportional

band setting in the System Set Up menu of the keypad/display

(default is 10%).

☐

If your system uses an RH transmitter, check the proportional

gain (Kp) setting in the System Set Up menu of the keypad/

display (default is 80).

☐

If your system uses an RH transmitter, check the integral gain

(Ki) setting in the System Set Up menu of the keypad/display

(default is 40).

☐

If your system uses an RH transmitter, check the derivative gain

(Kd) setting in the System Set Up menu of the keypad/display

(default is 0).

☐

If your system has an electronic drain valve, check the drain

duration (system dependent; see the table on Page 74).
