WIRE FUNCTIONSSECTION 3. WIRE FUNCTIONS1. Outdoor Sensor (2-Light Green Wires) are connected to the main controller on the Munchkin.Route wires from the Munchkin control to the external junction box, to your outdoor sensor, which willallow the user to change the temperature going to the Central Heating loop automatically. Place theoutdoor sensor preferably to the north or northwest or to the side which will be affected by changingweather conditions outside. NOTE: Do not locate the sensor in the direct sunlight.CAUTIONThe wire to outdoor sensor must not be laid closer than 6' to line voltage wiring(120/240 V) and must never be in the same conduit.Outdoor Sensor Function: The user can program the desired supply temperature based onthe heat transmitter (Baseboard, Radiant Floor, Air Handler) that will be used in the installation.Once the outdoor sensor (Light Green Wires) is connected to the heater, the water temperatureof the heater will adjust to run the heater more efficiently and provide greater comfort to the livingspace. See section 4: “Programming the Controller”.Connection Specification – Wire 22 AWG maximum to 100 feet or 18 AWG up to 150feet. Length of wire run cannot exceed 150 feet.2. Indirect Sensor (2-Light Blue Wires) are connected to the main control on the Munchkin.Route wires from the Munchkin control to the external junction box to the sensor (Included inThe Vision I Package) or the mechanical control Honeywell Part # L4080b-1395 (Not included inVision I Package) into the control well located in the front of the Super Stor Ultra Indirect FiredWater Heater. This will allow the installer to control the temperature of the indirect from theMunchkin and give the Super Stor Indirect Fired Water Heater priority over the Central HeatingCircuit. Once the Water Heater is satisfied, the Munchkin will then switch back to the CentralHeating Circuit only if there is a call for heat, otherwise the Munchkin will then shut down.Indirect Sensor Function: The Maximum run time on priority function for the Super Stor UltraIndirect Fired Water Heater is from 1-60 minutes. The Super Stor Ultra tank temperature can only beadjusted when using a sensor (not a mechanical control). Temperature adjustments are from 95 to185 degrees, plus a differential 1-18 degrees (Note: It is recommend that you do not exceed 5 minuteson the DHW pump post purge cycle to avoid cooling down your DHW tank). See section 4,“Programming the Controller”.Connection Specification – Wire 22 AWG maximum to 100 feet or 18 AWG up to 150feet. Length of wire run cannot exceed 150 feet.3. Indirect Circulator Lead (1-Pink Wires/1-Purple Wires/1-Green Wires) areconnected to the main controller on the Munchkin. Route wires from the Munchkin control tothe external junction box. Run the wire and connect it directly to the Super Stor Ultra Indirectcirculating pump. The purple wire will be your neutral lead and the pink wire will be your hot.This will supply 120 volts to the Super Stor Ultra Indirect Water Heater Circulator directly (TheCirculator is not supplied in the Vision-1 the Package).Indirect Circulator Program function: The Super Stor Ultra Indirect circulator program functionwill automatically start when the Super Stor Ultra sensor reads a call for heat, the installer can alsoprogram the post purge function on the circulator. The Post purge circulator function ranges from 1-30 minutes.Connection Specification – Wire 18 AWG maximum. Length of wire run cannot exceed100 feet.9
