Supply:
Stage 1: Variable output, 60 Hz, 10A FAN (3/4 HP/115VAC)/(1.5 HP/
230VAC), same phases as supply, fuse F1-15A slow blow.
Stage 2: Variable output, 60 Hz, 10A FAN (3/4 HP/115VAC)/(1.5 HP/
230VAC), same phases as supply, fuse F2-15A slow blow.
Stage 3: ON-OFF output, 115/230 VAC, 60 Hz, 30 VDC, 6A FAN, 10A RES,
heating or ventilation, fuse F3-15A slow blow.
Alarm: ON-OFF output, 115/230 VAC, 60 Hz, 30 VDC, 3A , fuse F4-3A slow
blow.
Probes: Low voltage ( < 5V), isolated from the supply. Operating range:
-40° to 120°F (-40° to 49°C). Accuracy: 1.8

Enclosure: ABS, moisture and dust-tight.
- 115/230 VAC (-18%, +8%), 60 Hz, L1 same phases as Stage 1
and 2, overload and overvoltage protection fuse F5-1A fast blow.
- 12 VDC for AC back-up supply; can activate Stage 3 and alarm
if supplied with 12 DC back-up voltage.
