WARMFLO II
Dual Heat System
Furnace Interface Controller and Control Voltage Installation
and Operations
Application – Heat Pump Multi-Wire Thermostat
Basic or Single Speed Heat Pump
WF-LGR4
As in previous interface modules, this is the plug-in controller for Electro-Mate EM-WU***** or EM-
WD***** plenum heater. Mechanical installation information is contained within companion installation
manual EI703 or EI707.
Also accompanying each system is a specific control program “chip”. This is typically part of ordering
information and should be listed on packing slip. A listing of these “chip codes” is in the controller setup
sections of this document.
This is an upgraded and improved WF-LGR3. Improvements are the response of field requests.
Thermostat wiring terminal block, pass through
Improved stat emergency heat function, no longer requiring extra relay
Reversing valve detection relay, positive WarmFlo and gas furnace interrupt during
cooling (RV logic pin jumper setup required)
Front panel “cool” light
Equipped for ECM blower motor, direct Y connection
Faster defrost response
Easier single cable plug-in to the upgraded (10-pin connector) WarmFlo II board
Reference Field Service Bulletin 1094 which relates to heat pump units with RV logic high for heating –
this unit identified as “Rev A” and has a control board identifier “WFIH46708A” includes revisions
relating to stat emergency “E” hookup and operation, cool light function, etc. Also study page 7,
determine the need for “stat-B” pin jumper.
Any applicationthis design assumes the connected room thermostat cannot and does not output an
emergency “E” function during cooling. During any and all cooling operations, this controller board “E WF”
and “E GAS” tab must be at 0 volts.
