Outdoor Sensor - heat-timer DiGi-SPAN Elite Series Installation And Operation Instruction Manual

System Pump Wiring
• Wire the two Yellow wires to the Slab Pump circuit. The relay should be wired to
break the power source hot leg. The relay is rated at a maximum of 1 Amp pilot duty
(Maximum of 1/8 HP) or 6 amp resistive load at 120VAC.
• The RSM-Elite System output does not source any power. A separate pump power
source is required. The relay makes when energized to switch the power to the pump.
Motorized Valve Wiring
• The valve motor must be of the floating type.
• The Red to Blue (Close relay) and Red to White (Open relay) connections are dry
contacts only. They do not source any power.
• The two valve relays are N.O. and each is rated at 1 Amp inductive load or 6A
resistive load at 120VAC.
• Connect the Red wire to the power source. The second wire from the power source to the valve
common terminal.
• Connect the Blue wire to the valve motor Close terminal.
• Connect the White wire to the valve motor Open terminal.
Wiring Input Terminals
Slab Supply and Return Immersion Sensor Installation
Supply (T1, COM), Return (T3+, T3-)
• Place the Slab Supply sensor in the header approximately 10' past the mixing valve before any
takeoffs where it will register the mixing valve output temperature.
• Place the Slab Return sensor where it will register the slab return temperature before mixing with
other returns.
• Only use the Standard Brass Tube sensors included with the control (HT# 904250-00).
• Each of the sensors must be inserted into a 3/8"ID 1/2"NPT immersion well (HT #904011-00).
• The sensor wires can be extended up to 500' using a shielded 2-conductor cable (Belden #8760 or
equivalent (#18/2)). Do not connect the shield at the sensor end. But, connect it to the
control COM and T3- terminals. Do not run sensor wires in conduit with line voltage
wiring.
Outdoor Sensor Installation
(T2, COM)
• Only use the Heat-Timer sensor included with the unit (HT# 904220-00).
• Locate the sensor in the shade on the north side of the building. It should never be in
direct sunlight.
• Be sure the location is away from doors, windows, exhaust fans, vents, or other
possible heat sources.
• The sensor should be mounted approximately 10' feet above ground level.
• Adhere the Outdoor Label provided to the back of the sensor base.
• Use the Enclosure Base bottom knockout for the conduit. Use the locknut to hold the
conduit and enclosure base together. Screw the cover to the base.
• If screws are used to affix the enclosure to the wall, make sure to seal around the sensor
and wall except from the bottom.
• The sensor wires can be extended up to 500' using shielded 2-conductor cable (#18/2).
Do not connect the shield at the sensor but at the control using the COM terminal.
• Do not run sensor wires in conduit with line voltage wiring.
Determining the proper location for the Outdoor Sensor is very important.
The RSM-Elite will base its operation on the outdoor temperature information
it receives from this location. If the sensor is in the sun, or covered with ice,
its reading will be different from the actual Outdoor temperature.
