1. OPTIONS AND ACCESSORIES AVAILABLE
A. Nortec Modulating Humidistat with Digital Display
(1)
NORTEC humidistats for GSTC or GSP Gas Steam humidifiers feature
proportional + integral control with setpoint range of 10-95% RH. The humidistat
connects directly to the low voltage terminal strip via 3 wires (shielded if run
exceeds 10 m). The humidistat accurately controls RH in a zone or space.

B. Humidistat with Integral Sensor and Controller with Digital Display
(1)
151-0142 - Modulating 0-10 VDC wall mounted humidistat, P + I control humidistat
with setpoint range of 0-95% RH. Connects directly to the GSTC or GSP low
voltage terminal strip via 2 wires (shielded if run exceeds 10 m) and accurately
controls RH in a zone or space. Time proportioning control not acceptable.
(2)
252-0266 - Modulating 0-10 VDC duct mounted humidistat, P + I control humidistat
with setpoint range of 10-95% RH. Connects directly to the GSTC or GSP low
voltage terminal strip via 2 wires (shielded if run exceeds 10 m) and accurately
controls RH in a zone or space. Can be used as a control humidistat if placed in
return air or as high limit if placed in supply. (Time proportioning control not
acceptable.)
C. Humidistat with Integral Sensor
(1)
150-9857 - Remote duct or modulating high limit sensor.
(2)
150-9858 - Remote wall mounted sensor.
(3)
252-0263 - Outdoor duct mounted temperature sensor. Can provide energy
savings and prevent window condensation by reading outdoor temperature and
resets the humidity control to prevent condensation.
