Snow Sensor Settings
TRIG TEMP – the temperature
•
which activates or de-activates
the RRSHA Hot Air Blower. The
value can be set from 34°F to
44°F.
DELAY OFF – the amount of time
•
the RRSHA Hot Air Blower
remains active after the
temperature rises about the TRIG
TEMP setting. The value can be
set from MIN (2 hours) to MAX (6
hours).
SENSITIVITY – the amount of
•
precipitation on the moisture grid
required to activate the RRSHA
Hot Air Blower. The value can be
set from MORE to LESS.
4. When finished, replace the front
cover of the Snow Sensor and install
the four mounting screws.
3.2 Adjusting the rod/crib circuit
startup delay timer
For RRSHA Hot Air Blowers with "Suffix R"
that power optional equipment, the Delay
Timer function powers the secondary circuit
after a short delay from the primary circuit's
start time (default delay time is two seconds).
This option helps reduce the startup
RRSHA Series Hot Air Blower User Manual
current draw, especially useful with lower
voltage systems like 240VAC single-phase
systems. Follow these steps to adjust the
secondary circuit's delay timer.
1. Open the RRSHA Hot Air
Blower's hinged cover door.
2. Open the cover of the control box.
3. The Rod/Crib circuit delay timer has
3 dials for adjustment.
The lower dial is a
functional adjust and set
to (A/Ai) for Delay-On.
The upper dial
determines the unit
value of time. The
middle dial is the unit
value time multiplier.
Default setting is
(A/Ai), (2), (1s):
Delay-On of 2 seconds

4. Set the upper and middle dials to
the desired delay-on start time for
the Rod/Crib circuit.
3.3 Adjusting GFI Sensitivity
(rod/crib circuit, only)
By default, each ground fault sensor is set to a
sensitivity rating of 40 milliamps. Follow these
steps to adjust the ground fault sensor
sensitivity for a circuit.
1. Disconnect the RRSHA Hot Air
Blower from its power source.
2. Verify the green LED on the Snow
Sensor is not illuminated.
3. Open the RRSHA Hot Air Blower's
hinged cover door.
4. Open the cover of the control box.
