are greyed).
Environmental:
Operating Temperature: -40 to 150°F (-40 to 65.5°C).
Shipping Temperature:
-40 to 150°F (-40 to 65.5°C).
Relative Humidity:
5% to 95% noncondensing.
Vibration:
Rated V2 level compliant.
Inputs/Outputs:
The W7750A Unit supports the following hardware features:
Three 20 Kohm NTC (1000 through 150,000 ohm) or 
PT3000 (250 through 12,000 ohm) resistive analog inputs 
(one reserved for space temperature and one reserved for 
the setpoint knob).
Three dry contact digital inputs (one reserved for the 
Bypass pushbutton).
LED digital output (only for the wall module LED) 2.5V at 3 
mA.
Six 24 Vac relay digital outputs (1.5A relays rated at 7.5A 
inrush current).
The W7750B,C Units support the following hardware features:
Four 20 Kohm NTC (1000 through 150,000 ohm) or 
PT3000 (250 through 12,000 ohm) resistive analog inputs 
(one reserved for space temperature and one reserved for 
the setpoint knob).
Two 0.2 to 10 VDC or 2 to 20 mA (user selectable) analog 
inputs.
Five dry contact digital inputs (one reserved for the Bypass 
pushbutton).
Eight on the W7750B (five on the W7750C) 24 Vac Triac 
digital outputs (500 mA MAX). The W7750C Unit also 
supports three 4 to 20 mA analog outputs.
LED digital output (only for the wall module LED, T7770 
models or LCD, T7560A,B) 2.5V at 3 mA.
One 20 Vdc power supply for auxiliary devices with a 
maximum current of 50 mA.
ANALOG INPUTS:
NOTE:
Only one of each type of input is allowed. For 
example, only one Outdoor Air Temperature sensor 
is allowed. No duplicate Outdoor Air Temperature 
sensors are usable on the same controller.
Space Temperature:
Type: RTD.
Supported Sensors: T7770A,B,C,D; T7560A,B.
Discharge Air Temperature:
Type: RTD.
Supported Sensors: C7100A1015*, C7770A1006, 
C7031B1033, C7031C1031, C7031D1062, C7031F1018 
(W7750B,C only), C7031J1050, C7031K1017.
Outdoor Air Temperature:
Type: RTD.
Supported Sensors: C7170A1002.
Return Air Temperature:
Type: RTD.
Supported Sensors: C7100A1015*, C7770A1006, 
C7031B1033, C7031C1031, C7031D1062, C7031F1018 
(W7750B,C only), C7031J1050, C7031K1017.
*The PT3000 sensor is not recommended for floating control 
(real time - discharge or return configured as space sensor). 
The PT3000 sensor is intended for monitoring or differential 
(staged) control
