Easy Heat RS2 Installation And Operation Instructions page 2

INSTALLATION INSTRUCTIONS
1. Mount the main housing under the soffit, or equivalent location protected from
the weather, using the screws provided. Refer to Fig. 2. Ensure that the mounting
location is close enough to the receptacle supplying power to the unit to allow the
cord on the control to be plugged in. The connection should be located for the best
protection from the weather and a drip loop used as appropriate. Drip loops should
be used between the control box and both the sensor wire and power connection
to the heater wire as appropriate for maximum protection. If desired, this receptacle
can be controlled by a switch (with a pilot light) located inside the house. See Fig. 2.
2. Lay the Splice Connection and sensor wire along the bottom of the gutter within
two inches of the roof de-icing cable. Route the sensor wire over at least one gutter
support strap or nail in order to sense the full depth of the gutter, then route along
one triangular weave of the heating cable on the roof as per diagram. At the peak
of the second triangle, attach the sensor wire up the roof, at least 2 feet (60.96 cm)
past the heater wire as illustrated. Use the clips provided to secure the sensor wire to
the roof. Gently squeeze the coated end of the clip around the sensor wire. See Fig. 3.
3. Connect the cord from the roof cable to the Roof Sentry Control box. Cables up to a
maximum of 1200 Watts can be used.
4. Plug the Roof Sentry cord-set into the receptacle. Ensure that this connection
remains dry.
5. If using a pilot light, turn the pilot light switch to the "ON" position. The pilot light on
the plug of the unit will be lit.
6. Your Roof Sentry is now ready to control the cable on your roof.
7. The power light indicator (next to the receptacle on the control box) will only be lit,
when the roof de-icing cable is energized. Fig. 4.
8. For Roof without gutter- Lay the sensor wire along the triangular weave of the
heating cable as shown on Fig. 5 and secure the main housing under the eave of the
roof as shown on Fig. 5.
9. The RS2 may be used on metal and membrane roofs. Typically installation of the roof
clips on these types of roofs requires an adhesive be used to bond the clip to metal
or membrane material. The choice of adhesive is left to the installer. Care must be
taken on metal roof installations to ensure the sensor wire is protected from sliding
snow or ice, which could damage the sensor wire and render the RS2 inoperable.
Prior to installing on a membrane roof ensure the sensor wire will be able to reach the
area where melting is occuring, The RS2 sensor wire cannot be extended.
OPERATION INSTRUCTIONS
The roof control is designed to energize the roof de-icing cables
ONLY when roof snow/ice melting conditions exist AND there is
a risk of this melt water refreezing at the roof edge to form an
ice dam. This ensures that ice dams will not form and that energy
consumption is minimized.
The RS2 senses the ambient temperature. The sensor wire senses
the presence of water. If the temperature is below about 4°C
(40°F) AND at least 10 inches (25.40 cm) of the sensor is laying in
(or on) water, then the RS2 will apply power to the roof cable.
Note that snow or ice surrounding the sensor wire WILL NOT result
in activation of the RS2 to energize the cables.
The RS2 is provided with a "Self Test" function mode; when it is
first energized or when it recovers from a power outage, the
"Power Indicator Light" will turn on for 2 minutes if at least 10
inches of the sensor wire is submerged in water regardless of the
ambient temperature. The Power Indicator Light will then turn off
and the Self Test function will be completed. The RS2 will return to
normal operation in about 25 minutes.
Disconnect the power to the RS2 during summer months.
At the beginning of the heating season and monthly during
operation, inspect the RS2 control and its connection to the
electric power source. Discontinue use and remove any unit that
has been cut, damaged, or has deteriorated for any reason.
Other conditions to look for are chewing by animals or any
physical abuse. This RS2 does not contain any serviceable parts.
Inspect for and remove all leaves and combustible debris from
roof, gutters and downspouts.
