Parameter A0 must be set to 4. Parameter A2 must be set to 0.
Alarm Output:
The H terminals allows connection to an on-board SPDT alarm relay that provides
No and NC contacts for remote indication of alarms.
Dehumidify Output:
Dehumidify contacts are also provided which can be used to control a dehumidifier
from the humidifier control system (stand-alone modulating mode only). The
contact is rated for 250 Vac, 8 Amp resistive and 2 Amp inductive loads.
For Modulating Operation with External Controller:
Connect any external controller (0-1 Vdc, 0-10 Vdc
Parameter A0 must be set to 1.
Parameter A2 must be set per the OUT signal from the
regulator:
• voltage: 0 to 1 Vdc; 0 to 10 Vdc; 2 to 10 Vdc;
• current: 0 to 20 mA; 4 to 20 mA.
NOTE: Safeties are high-limit humidistat, air flow
switch, and/or external enable.
For Stand-Alone Modulating Operation:
Connect a high limit sensor and control sensor per the
diagram at right.
Parameter A0 must be set to 2 if no high limit sensor, 3
if a high limit sensor is used.
Parameter A2 must be set per the OUT signal from the
sensor:
• voltage: 0 to 1 Vdc; 0 to 10 Vdc; 2 to 10 Vdc;
• current: 0 to 20 mA; 4 to 20 mA.
Terminal 4I (+(G)) = 12 Vdc
Terminals 2I & 6I (M) = common
For Steam Baths (Turkish Baths):
In this case a temperature sensor is used to control the
humidifier. Connect sensors per the diagrams below.
