    GF-126 Boiler Valve Controller (BVC) User Manual OMM-0051_0D 1. FOREWARD The AERCO Boiler Valve Controller (BVC) is designed for variable flow heating systems. The BVC can be configured to control each motor operated valve (MOV) independently to minimize the system flow requirements in a multiple boiler plant. Using the BVC in your system design will save energy, help eliminate over-temperature faults and improve the life and reliability of your AERCO Boilers.

    GF-126 Boiler Valve Controller (BVC) User Manual OMM-0051_0D 3. GENERAL INFORMATION 3.1 INTRODUCTION This User’s Manual provides the installation and operation procedures for the AERCO Boiler Valve Controllers (BVCs). Currently, the Boiler Valve Controllers are available in six different models with capabilities as described in the table below. These Boiler Valve Controllers permit AERCO Benchmark and KC1000 Boilers to be used in variable flow systems, while eliminating the need for a dedicated bypass line.

    GF-126 Boiler Valve Controller (BVC) User Manual OMM-0051_0D Figure 1: The AERCO Boiler Valve Controller Box 3.4 USE OF THE BOILER VALVE CONTROLLER There are two basic purposes of the BVCs. They are as follows. 1) Reduce the required minimum system water flow to minimal single boiler flow. 2) Eliminate the need for a boiler bypass flow path by being able to open up flow through the boilers when system demand is satisfied, thereby preventing system pump dead head conditions.
