Description: Tired of replacing spring return damper motors that get hot and burn out? The Belimo LMB24-3-T is one of the finest damper motors on the market today, with a 5 year factory warranty and outstanding reputation. This kit gets the premier commercial grade Belimo LMB24-3-T damper motor and adapter kit for about the same price as the the stock 2 wire spring replacement motor. This kit works on most dampers that have a Hansen, Synchron, or Cramer 2 wire "spring return” motor that has the same output shaft shown in the last picture (motor with 2 yellow wires). MAKE SURE the output shaft of your motor looks like the one in the last picture, the motor with the two yellow wires. If not, our ebay store damperdirect has many other retrofit kits and adapters to get almost any damper back in business - your satisfaction is guaranteed! Check the 5 digit number on the side of your Synchron motor that ends in an "R" or an "L". This kit will retrofit (with the much finer Belimo LMB24-3-T actuator), any motor that has the cross pin end on the motor shaft. These numbers will cross over to this kit: 37789R 38766R 39154R and 38929L. This listing is for a Belimo LMB24-3-T motor and retrofit kit - to include the Belimo LMB24-3-T motor, shaft adapter, capture bracket, anti-rotation bracket, and 2 self-tapping sheet metal screws shown in the first picture. Anything else in the other pictures is for illustration purposes only. PHOTOGRAPHS: 1. This is what you get with this retrofit motor kit - any items shown in other pictures are for illustration purposes only. 2. Belimo LMB motor shown mounted to old damper with old take off Synchron motor in foreground. This retrofit kit works on round dampers as well. 3. The slotted input of the damper is shown after the old motor is removed. 4. Illustrated instructions - also available on how to hook up this 3 wire motor to a zone control panel with only 2 damper output terminals. 5. Brackets from kit mounted on damper before motor is installed with damper is laying on its side. 6. Another picture of Belimp LMB24-3-T motor mounted on the old damper. 7. Old take off Synchron brand motors - remove your old motor and make sure your old motor has the identical output shaft with cross pin as Synchron motors were made with many different outputs. SPECIFICATIONS: Retrofits the industry leading LMB24-3-T motor on to many residential dampers, including many Lennox, Young Regulator, Enerzone Systems Corp., RetroZone™, Jackson Controls, and others who used this style of Synchron or Cramer motor. Gets rid of spring return motors for better reliability and energy savings.Works with any brand of standard 24vac zone control system.Saves energy, extends motor life, far more powerful motor with 5 year warrantyRequires 3 wires to motor and the mounting of the anti-rotation bracket with 2 self tapping screws, included.24vac 2 va damper motorPart no. LMB-K3 Spring return damper motors pull 8 to 10 va of continuous power since they must overcome the return spring. Besides wasting energy, the spring return motors get very hot, contributing to their often premature failure. The Belimo LMB24-3-T retrofit kit motor uses just 2va for 90 seconds, and never even gets warm to the touch! A five year, best in the business, warranty - so stop replacing those overpriced spring return motors! Your current damper has just 2 wires to the motor - will this 3 wire motor work? Yes, but you will need a third wire from the zone control panel or thermostat to allow this 3 wire motor to work. Very often, standard 4 wire thermostat wire will have been used, so check the cable for extra wires. Most zone control panels support 3 wire motors, including all Honeywell panels. Check your zone control board damper outputs for an unused terminal. If your damper outputs are labeled M1, M4, and M6, OR Power Open PO, Power Close PC, and Common C, you have all the outputs you need and are good to go. Even if your zone panel has just 2 damper outputs, you can still use this kit since the Belimo LMB motor will accept an alternative wiring procedure that places full time 24vac power on terminals 1 and 2, and then uses the current zone board output for terminal 3.
