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. Installation options: On the wall with a BUS connection to a heat source or CZM100 module with an EMS-BUS Interface (Energy Management System).

Bosch has just introduced a new Greenstar Combi 131 Gas-Fired Wall-Hung Condensing Boiler for space heating and DHW.  "Combi" (combination) unit with space heating and integrated water heating in one highly efficient, compact unit. With special insulation to ensure ultra quiet operation and the exclusive keypad safety lock feature to prevent unwanted tampering with heating controls, this unit is the ideal "green" upgrade for detached & terraced houses and is also suitable for apartments.

The Greenstar Combi 131 is simple to operate and some of the specifications include:

131.9K BTU 

AFUE rating of 95%

Delivers 3.2 GPM at 72 degree rise

3/4" Water connections

1" main heating connections

Can be vented with 2" or 3" PVC

3" PVC concentric vent kit available for vertical or horizontal installation

Telescopic Concentric Up and out vent kit available for horizontal installation 

The energy-savings and environmental features are:

Aluminum-Silicon heat exchanger delivers high efficiency with low temperature applications

Low NOx emissions ahead of 2012 SCAQMD regulations

Simple, intelligent control options optimize efficiency and fuel consumption

Low electrical consumption when the boiler is in standby mode

Electronic ignition

Anti-cycle and modulation control

These Greenstar Combi 131 condensing space heating boiler can be used for either Natural Gas or Liquid Propane installations.   The Greenstar units come preset for Natural Gas (NG), but can be converted to Liquid Propane (LP).  A gas conversion kit is included.

The Greenstar Combi units come with a temperature control FW 200 that can either be mounted to the heater or mounted to the wall beside the heater.  This module allows the heater to be set for different temperatures, zones and the time of day the heater comes on and goes off.  The FW 200 control also comes with a temperature probe that goes to the outside and detects and monitors the outside temperature and then allows the heater to remember the coldest and warmest times of the day and year.

All Greenstar Combi boilers are equipped with a high-strength stainless steel secondary exchanger and burner with double passage - ensuring consistent temperature output based on demand. The DHW hot water temperature control limit of 140°F helps prevent scale build-up within the heat exchanger.
