Global Protankless Supply would like to announce that Bosch Thermotechnology is no longer supplying the CZM100 Zoning module 7738110112 for Bosch Greenstar Boilers.  The CZM100 is now discontinued due to the factory where these are made was in the Ukraine.

If you are looking for third party zone manager for the Bosch Greenstar boilers any brand third party control works. Taco, Honeywell, Tekmar, any brand that manages a boiler that has “dry contacts”. All condensing boilers in the USA have two “dry contact” terminals, so the connection is no different than anything else (Navien, Lochivar, NTI, all brands).

For multiple third party zone managers being used this would depend on the third party controllers. Some brands have 3, 5, 6, or more zone controls in a single box. Some will daisy-chain or cascade control boxes. That is up to that control manufacturer. We only need to get a signal on our terminals “TT” to energize or de-energize the boiler.
