Controller Performance Specifications
Power:
W7752D and W7752E; W7754K,M,N,P
230 Vac +10%, -15%, 50/60 Hz.
W7752F and W7752G
115 Vac +10%, -15%, 50/60 Hz.
W7752J
100 Vac ±6%, 50/60 Hz.
W7754L
24 Vac ±20%, 50/60 Hz.
Operating Temperature:
32...122°F (0...50°C).
Shipping/Storage Temperature:
-40...+158°F (-40...+70°C).
Relative Humidity:
5% to 95% non-condensing
Inputs:
Temperature Sensor:
20k ohm NTC
Setpoint Potentiometer:
10k ohm
Digital Input:
Closed ≤ 400 ohms
Open ≥ 10 K ohms
Outputs:
Triac voltage range:
24 Vac ± 20%.
Triac max. current ratings:
250 mA continuous
650 mA surge for 30 sec.
IMPORTANT:
When any device is energized by a triac, the device
must be able to sink a minimum of 15 mA. If non-
Honeywell motors, actuators, or transducers are to
be used with Excel 10 FCU Controllers, compatibility
must be verified.
Fan relays voltage range:
20 to 253 Vac
Fan relays max. current rating:
3 A
Electric reheat relay voltage range:
20 to 253 Vac
Electric reheat relay max. current rating:
10 A
6 A (UL916)
Interoperability
The Excel 10 FCU Controllers use the LonTalk protocol. They
support the L
