Bosch Heatronic 4000 by Bosch Home Comfort

Commercial Boiler Control Heatronic 4000 Don‘t let its small size fool you, the Heatronic 4000 is a powerful control packed with functionality. Designed for easy and intuitive set-up, the Heatronic 4000 is pre-loaded with the parameters for Bosch and Buderus commercial boilers.

A Flexible Control Solution for Light Commercial and Large Scale Residential Applications. The Heatronic 4000 is a cost effective control that works with up to four condensing and non-condensing boilers that are either modulating, single stage or two stage. Designed to accurately maintain target water temperature based on outdoor temperature reset or a fixed setpoint for space or process heating applications. Optional features to increase efficiency and boiler plant reliability include domestic hot water and setpoint heating, boiler run-time balancing,

Features

standby primary pump operation, and pump exercising.

▶ Control and monitor up to 4 boilers in any combination of condensing and conventional models

Remote monitoring and adjustments for the Heatronic 4000 are possible with Building Automation Systems - BACnet® or Modbus® Bosch and Buderus boiler parameters are pre-programmed in the Heatronic 4000 for ease of set up. Installing the Heatronic 4000 will save energy and further reduce the overall energy bill. BoschHeatingAndCooling.com

▶ BacNet® and Modbus® compatible ▶ Programmable scheduling DHW priority and Outdoor temperature reset ▶ Compatible with modulating, single stage, two stage and dual fuel burners, for NG, LP and oil fuel types ▶ Pre-configured with over 20 parameters for all Bosch / Buderus commercial boilers
