SEQUENCE OF OPERTION CWMV includes supply air blower, hot water coil, and blower control. circulating pump can be ordered extra for field installation. fter a 45-second (fixed) timed-on delay the blower energizes at heating speed. fter a 30-second (fixed) timed-off delay the supply air blower shuts off. PPROVLS Units certified by CS International. lower data from unit tests conducted in Lennox Laboratory air test chamber. PPLICTION CWMV can be used with properly sized gas-fired or oil-fired water heating devices. Cannot be used with potable water. Supply air blower moves the return air past the coil to extract the heat and then distribute the heated air throughout the conditioned space. CWMV is a multi-position (upflow, downflow, or horizontal) blower/hot water coil unit. Lennox add-on indoor coil with remote air conditioning unit, air cleaners, automatic humidifier, and all Lennox Indoor ir Quality products can easily be added for a complete all season system. Zoning pplications Units may be used with certain zoning systems. Zone control panel must be able to interface and communicate with the variable speed blower motor in the unit. Lennox Harmony III Zoning System has this capability. E HETING SYSTEM Hot Water Coil Corrugated/lanced aluminum fins. Seamless corrosion resistant copper tubes. Fin collars grip tubing for maximum contact area. Flared shoulder tubing connections and silver soldering provides tight, leakproof joints. Factory tested under high pressure. Entire coil accessible for cleaning. Freezestat Protects system from freezing temperatures when unit is installed in unconditioned areas. Thermostat automatically energizes circulating pump when water line temperature falls below 45 F. Optional ccessories Circulating Pump ronze construction, Non-metallic impeller with Carbon bearings. Self lubricating. Impedance protected. D Motor and impeller removable as single unit for servicing. CWMV / Page

LOWER Variable Speed lower Motor Variable speed motor (VSM) maintains specified air volume from 0 though 0.80 in. w.g. static range. Gradual acceleration and deceleration of variable speed blower motor when starting and stopping over a specific time frame results in extremely quiet operation. Variable speed operation is achieved by the use of an ECM (Electronically Commutated Motor) motor. Motor is controlled by Electronic lower Control. Motor is resiliently mounted. When units are used with Harmony III Zoning System, blower motor operates from predetermined minimum to maximum air volumes to satisfy zone requirements. Variable Speed lower Each blower assembly statically and dynamically balanced. Change in blower speed is easily accomplished by simple jumper pin position change on Electronic lower Control. lower assembly completely removable for easy servicing.

4 E FETURES CONTROLS Electronic lower Control Interfaces variable speed motor with thermostat. Controls evaporator humidity by controlling blower and compressor speed on two-stage outdoor units. Two COOL speeds and one HET speed (with four different air volume selections for each) are made by simple jumper pins on board. DJUST jumper pin allows approximately 0% higher, normal, or 0% lower motor speed selection within HET and COOL speeds selected for fine tuning the air volume. DELY jumper pin allows selection blower motor dehumidification profiles during cooling mode. Option - Motor runs at 00% of capacity until demand met. Once demand is met, motor ramps down to stop. Option - Motor runs at 00% of capacity until demand is satisfied. Motor runs at 00% of capacity for 60 seconds then ramps down to stop. Option 3 - Motor runs at 8% of capacity for approximately 7-/ minutes. If demand is not satisfied, motor runs at 00% capacity until demand is satisfied. Once demand is met, motor ramps down to stop. Option 4 - Motor runs at 50% capacity for 30 seconds, then 8% capacity for approximately 7-/ minutes. If demand is not satisfied, motor runs at 00% capacity until demand is met. Once demand is met, motor runs at 50% capacity for 30 seconds, then ramps down to stop. Control has two diagnostic indicator lights, CFM and RUN, to assist in servicing. ccessory relay terminals provide connections for power humidifiers or electronic air cleaners. Control is factory installed in the unit control box. 4 Volt Transformer Furnished in CWMV control box. Optional ccessories ComfortSense 7500 Touchscreen Thermostat Electronic 7-day, universal, multi-stage, programmable, touchscreen thermostat. 4 Heat/ Cool. uto-changeover. Dual-fuel control with optional outdoor sensor. Controls dehumidification during cooling mode and humidification during heating mode. Offers enhanced capabilities including humidification / dehumidification / dewpoint measurement and control, Humiditrol control, and equipment maintenance reminders. Easy-to-use, menu driven thermostat with a back-lit, LCD touchscreen. See the ComfortSense 7500 Product Specifications bulletin in the Controls section for more information.
