 LMB24 Kit4

 

Belimo Damper motor Kit for Synchron-Enerstat, Lennox, Jackson, Retrozone, Young

 

 

 

Tired of replacing spring return damper motors that get hot and burn out?

 

The Belimo LMB24 is one of the finest damper motors on the market today, with a five year factory warranty and outstanding reputation. This kit gets the premier commercial grade Belimo LMB24 damper motor and adapter kit for about the same price as the the stock 2-wire spring replacement motor. This kit will also work on almost any damper where the original motor had the output shaft of the Synchron motor shown in the last picture (motor with 2 yellow wires)

 

 This kit works on most dampers that had a Hansen Synchron or Cramer 2- wire "spring return” motor that has the output shaft shown in the  last picture.  

 

MAKE SURE the output  shaft of your motor looks like the one in the last picture, the motor with the two yellow wires. Check the 5 digit number on the side on your synchron motor, that ends in an "R" or an "L". This kit will retrofit any motor, with the much finer Belimo LMB24, that has the Cross pin end on the motor shaft.  

 

These Synchron numbers will cross over to this kit: 

 

37789R      38766R       38929L         39154R

 

The Belimo LMB24 Kit4  includes the Belimo LMB24-3-T motor, shaft adapter, capture bracket, anti rotation bracket and two self tapping sheet metal screws shown in the first picture; anything else in the other picture is for illustration purposes only.

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 warranty is best in the business, so stop replacing those overpriced spring return motors!  

 

Your current damper has just two 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 three 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 two 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.  Full illustrated instructions are included.
