CONTROLSEIMiComfort Residential Communicating Control SystemEquipment Interface Module (EIM)Bulletin No. 210662August 2015Supersedes March 2014P R O D U C T S P E C I F I C AT I O N SThe Equipment Interface Module (EIM) allows aniComfort Thermostat to be used with most noncommunicating HVAC systems.The EIM allows most conventional, non-communicatingfurnaces or air handlers (up to 3 stages heatingand 2 stages cooling) to emulate an iComfort enabled communicating indoor unit (with reducedcommunication features).NOTE - Most conventional outdoor/indoor unit and mostiComfort -enabled 1outdoor units can be used in thesystem.1NOTE - Not for use with XC25 or XP25 outdoor units.See table on page 3 for available systemconfigurations.Additional conventional (not iComfort -enabled)indoor air quality comfort products (PureAir AirPurification System, Healthy Climate Humidifiers,Humiditrol Enhanced Dehumidification Accessory,Healthy Climate Energy/Heat Recovery Ventilators,Healthy Climate Germicidal Lights) can be added for acomplete total-comfort system.EIM MODULEContains all necessary relays and controls to emulatean iComfort -enabled indoor unit.Terminal ConnectionsCommunicating RSBus - To iComfort thermostat: R, I , I–, CNon-Communicating - To conventional indoor/outdoor unit:Module has two green LEDs. One indicates status andaids in troubleshooting, a second LED indicates RSBuscommunication. W1, W2, W3, G, Y2, Y1, C, DS, R, H, O, BAny system alerts/warnings are transmitted to theiComfort Thermostat.Connections are also furnished for an Outdoor AirTemperature Sensor and Discharge Air Sensor. Sensorsmust be ordered separately.Serial communications bus (RSBus), with less wiringthan a conventional heating/cooling system, allowssystem communication. Uses 4-wire, 18-gaugestandard thermostat wiring for connection to theiComfort Thermostat.Conventional thermostat wiring connects the EIM tothe non-communicating indoor/outdoor unit equipment.See System Components on page 2 for additionaldetails.Jumpers are furnished for the following settings: U nit Type: IFC (furnace) or AHC (air handler). Defaultsetting is furnace. N umber of Heat Stages (0, 1, 2, 3). Default setting is1 stage. H eat Pump Capacity (1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 5.0).Default setting is 3.0. For non-communicating heatpumps.Dual-Fuel - To non-communicating heat pump: DFTS, w1-DEF, O, BNOTE - Outdoor Air Temperature Sensor is furnished asstandard with iComfort -enabled outdoor units.Blade-type 3 amp fuse protects module.CASEConstructed of high impact ABS plastic.Hinged cover with latching tabs prevents tampering.Can be mounted on the side of the indoor unit or anearby stud or wall.Dimensions (H x W x D): 6-1/8 x 7-1/2 x 1-3/8 in. (156 x191 x 35 mm)Weight: 1 lb.EQUIPMENT WARRANTYFive years in residential installations and one year innon-residential installations.Refer to Lennox Equipment Limited Warranty certificateincluded with unit for specific details.
