CZM100 Zoning module for Bosch Greenstar Boilers Now Discontinued

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.

Bosch Greenstar Wall-Hung Boilers Now Come With CRC200 Comfort Room Controller

All of the Bosch Greenstar Wall-Hung boilers now come with the CRC200 Comfort Room Controller.  The Wall-Hung Greenstar boilers used to come with the FW200 Weather Compensating Controller but that is now sold as an accessory. The Bosch Greenstar Floor-Standing boilers do not come with a thermostat.

The CRC200 is a programmable controller with an integrated temperature sensor and can be used as a boiler control or in conjunction with the CZM100 Comfort Zone Manager as a room controller. It comes with back light and features a time program for heating and indirect hot water tank.

The user interface is used to control a heating zone and a Domestic Hot Water (DHW) tank charging circuit for water heating directly at the heat source. The user interface displays information about the heat source and heating system and is used to change the settings.

A maximum of 8 heating zones is permitted when connected to several CZM100 Comfort Zone Managers. Water heating may be controlled with or without time program.
