Introduction When installed according to this installation manual and inspected by your local power company representative, your dual heating system will qualify for special off-peak electric or dual fuel kWh rates. Easy and direct connection for the utility load control receiver, both winter and summer control.
Installation Requirements 1. All installation work must be performed by trained, qualified contractors or technicians. Electro Industries, Inc., sponsors installation and service schools to assist the installer. Visit our web site at electromn.com for upcoming service schools. WARNING ALL ELECTRICAL WIRING MUST BE IN ACCORDANCE WITH NATIONAL ELECTRIC CODE AND LOCAL ELECTRIC CODES, ORDINANCES, AND REGULATIONS. WARNING OBSERVE ELECTRIC POLARITY AND WIRING COLORS.
Mechanical Installation – Upflow For downflow or horizontal see appropriate section. This upflow section provides more illustrations and details. The installer should review this section and then relate the comments under downflow or horizontal as they apply. This WarmFlo Select unit is installed above the A-coil as shown below. N or W coils – for close coupling to the refrigerant coil, only A-coil is approved.
Step 2 Measure plenum width and depth a. Step 1 determines facing side (hole cut decision) b. Width 17” or less – 15” model 18” or 19” – 18” model 20” to 22” – use side baffles as detailed in C-1 23” or greater – must field construct baffling as shown in C-2 c. Depth 20” or less – no baffling 20” or greater – need rear baffling as detailed in C-2 Step 3 Cut insert hole a.
Step 4 Add necessary baffling a. See Step 2 for determination and if required Step 5 Insert unit and bolt in place a. Extend center V deflector to plenum depth b. Do not drill into refrigerant lines c. Note airflow decal d. Seal as required Step 6 Install WarmFlo sensors a. Outdoor (OT) – extend to best location, mount with tip up Attempt to shade from direct sun, north side is preferred See electrical section with additional sensor details b.
Airflow Page 1 specification chart shows maximum temperature rise at 55° F. This is simply good HVAC practice and duct works/furnace blower design. The WarmFlo Select controller and its sensing will take care of itself but there is more to the story. It is true that the WarmFlo Select modulating control and the supply sensor adjust the electric heat or element capacity based upon temperature.
WarmFlo supply sensor installation – notice spacing and positioning comments on drawing EA104. Basically this sensor needs to be in a major air stream, about 20 airflow inches away from the actual electric element. Installation, wiring – except for a shipped loose (included) second hi-limit probe, all electrical, hookup, operation, etc. is basically the same as the upflow model. This additional hi-limit probe is code required for downflow.
Electrical Hookup WARNING DISCONNECT ALL ELECTRICAL POWER BEFORE ELECTRICALLY CONNECTING OR SERVICING THE UNIT. FAILURE TO DISCONNECT THE ELECTRICAL POWER BEFORE WORKING ON THIS PRODUCT CAN CREATE A HAZARD LEADING TO PERSONAL INJURY OR DEATH. Line Voltage The nameplate and/or Installation and Operating Manual specification page provides kW rating and operating current requirements. Select the proper wire size to comply with your type of wire routing and NEC field wiring requirements.
Use care in selecting location so the sensor does not pick up false temperature from the heat pump outdoor unit, from refrigerant line sets, dryer vent, reflection off of steel siding, etc. Also do not install the sensor in a plastic box because it will falsely trap and pick up radiant sun temperature. Other Sensor Related Comments The factory supplied OT cable is 25 feet. If additional cable length is required, you must use the following rules for extending the cable.
WarmFlo Select, TB3 Connection The WarmFlo Select control board must have specific wired connections to the gas furnace and outdoor unit. This hookup wiring takes place on the left center of the control board, hinged door open. See drawing EH711.
Field Setup or Programming Evolution/Infinity stat setup menu – it is extremely important and required that the roomstat setup menu be reprogrammed as shown below. This list highlights the items which are important for WarmFlo Select combination and is not the complete setup menu. THERMOSTAT SETUP MAXIMUM CYCLES PER HOUR: 4 ANTICIPATOR: 3 ◄ BACK 10 kW, 3-ton or smaller.
FURNACE SETUP OFF DELAY: 120 SEC. SWITCH SW4-3: OFF (CHANGE AT FURNACE) ◄ BACK FURNACE SETUP G TERMINAL: NEXT ► HEAT PUMP SETUP COOLING LOCKOUT: 55° F LOW AMBIENT COOL: NO DEFROST INTERVAL: 90 MIN. QUIET SHIFT: OFF HIGH COOL LATCH: OFF HIGH HEAT LATCH: <50F FAN ◄ BACK ◄ BACK High heat latch – 50° F. HYBRID HEAT SETUP OUTSIDE LOCKOUT TEMPS FURNACE LOCKOUT: NO HEAT PUMP LOCKOUT: NO DEFROST W/FURNACE NO HP TO FURNACE STAGE TIME: 60 MIN. ◄ BACK Furnace lockout – NO (default).
Important This special model has its own programming chip. The unit as received should include version 17.*. If this is not the case there will be an immediate error when power is turned on. Minimum Warm Air This dial switch sets a “floor” or minimum operating temperature level. The supply temperature will never go below this point independent of outdoor temperature, heat pump output, etc. 0 = 90 1 = 92 2 = 94 3 = 96 4 = 98 5 = 100 6 = 102 7 = 104 Factory set on #3.
Operation Indicators Front Panel LED’s - Hi-limit – when the hi-limit probe (automatic reset or manual reset) opens this top red LED is on. The electric elements will be interrupted via a safety relay circuit whenever this HL LED is illuminated. PWR ON – indicates good fuse and 24-volt power source from the furnace terminal block.
Handheld Analyzer/Laptop Software This test tool and/or software is available for temperature offset, field altering the program chip parameters and setup, and general assistance for troubleshooting. However, for this special version 17.10 software the factory or setup defaults, read out and controlled are different. The WF-ANZ*, version 4.12 update, now can be used to real time calculate CFM.
See pages 9 and 10 and review routing comments Bad sensor, operating default condition – the detection of bad sensor forces the controller to a fixed stage operation.
Installation Checkout Insert plenum thermometer 6” to 8” above the electric element section, position to measure the warm air from the electric elements. Proceed with the following procedure, observing the various staging action, element power current, and the outlet temperature. Turn on system in heat mode and verify proper heat pump and WarmFlo Select operation. o If it is above 50° F OT, the electric elements may be disabled within the internal logic.
