heat-timer DiGi-SPAN Elite Series Installation And Operation Instruction Manual page 2

The Curve value compensates for both different slab types and different outdoor weather conditions. After making a change in
the Curve value, it is necessary to wait at least several hours before accessing what affect it will have on slab temperatures.
The RSM-Elite will control a 3-way motorized mixing valve to regulate the amount of heat being supplied to the slab. The motorized valve
will mix the heated fluid from the heat source with the fluid returning from the slab.
Mounting the Controller
• The RSM-Elite is designed to mount on a 1900
(4"x4") deep electrical box.
• If additional room is needed for wiring use the
extension skirt provided in the box.
• Place the RSM-Elite in a convenient location near
the unit to be controlled.
• Mount the RSM-Elite indoors and away from
excessive heat or cold.
• Partially unscrew the Display Cover Mounting
screws. This allows for its removal.
• Lifting the Display Section away from the base will
unplug it from the Base section.
• Proceed with the power and output wiring
instructions.
• Use the screws provided to mount the RSM-Elite
to the 1900 box or the extension skirt.
• Mount Display Section back to the Base Section.
Tighten the Display Cover Mounting Screws.
Wiring
Wiring Power Input
The RSM-Elite is designed to accept ONLY A SINGLE POWER SOURCE. It can be wired to either 120VAC using the two Black
wires or 24VAC using the right most two terminals on the terminal block on bottom of the control. Heat-Timer recommends the
installation of a Surge Suppressor and a Power Switch before the Power Line connection for safety and ease of service.
120VAC
• Attach line voltage, 120VAC, to the two Black wires extending from the back of the RSM. Remember to use the power line from a
different source than the equipment being controlled.
24VAC
• Use a dedicated transformer with at least a 5VA output.
• Bring 24VAC to the two right most terminals on the front of the RSM-Elite marked 24VAC and COM.
Wire Colors and Output Lights
• The RSM-Elite has a three S.P.S.T. (single-pole single-throw N.O.) relays. Each output is rated at 1 Amp inductive load or 6A
resistive load at 120VAC.
• The RSM-Elite has three lights that follow the output relays operation. When a relay energizes, its LED will turn on.
• The outputs are dry contacts only. They do not source any power.
• The two Yellow wires represent System Output relay and the right LED. The System output can control the Slab supply pump. See
System Pump Wiring on page 3.
• The Blue wire represents the Valve Close Output relay and the left LED.
• The White wire represents the Valve Open Output relay and the middle LED.
• The Red wire represents Valve Common. This wire must be connected to the valve power source. See Motorized Valve Wiring on
page 3.
