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.
(2) Humidistat Specifications:
(a) Operating Conditions: 41ºF-122°F (5°C-50°C)
(b) Control: 0-95% RH non-condensing
(c) Sensor: 0-100% RH
(d) Humidity Sensor: Solid-state humidity sensor. Suitable for normal, clean air.
Not to be used in corrosive or harmful environment.
(e) Resolution: +- 0.1%
(f) Repeatability: 0.5%
(g) Accuracy of Sensor: +/- 3% RH from 0-100% RH Range: 10-90% RH for
32°F-122°F (0°C-50°C)
(h) Temperature Effect: 0.05% /°F
(i) Outputs: 0-10 VDC
(j) Power: 24 VAC -15%, +10% 50/60 Hz; 2 VA
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.
