Multi-Unit Controller

 

   A large system of PHH-32, 9.5.8.4 or 28c series Palomas can be electronically controlled with the MIC-185 Manifold Controller. For systems of 7 to 20 units, the MIC-185 Controller needs an extended communication board, the MICS-180, which can be fit inside the MIC-185 installation box.

   The MIC-185 Controller is linked to each Paloma with a separate communication cable. Temperatures are set for the entire system by a single Main Controller (UMC-117), which is linked directly to the MIC-185. The Main Controller will also display diagnostic codes for each unit in the system.

   The PHH-32, 9.5 or 28c Series is designed to meet the demands of high-volume hot-water applications, whether they need 8 gallons per minute or 80. In a residence, a multi-unit system may be needed to feed a multi-head shower system, whirlpools, or a Roman bath.  In commercial applications, we see this requirement at apartment complexes, hotels and campuses.

   Systems controlled by the MIC-185 have the same minimum ignition flow as a single unit. In the 28c Series, this is just 0.66 GPM and in the 9.5.8.4 and PHH Condencing series, this is just 0.44GPM.  The MIC-185 Controller is also designed to maximize the life of the system by rotating the order of ignition and distributing heating load among the units.

PH-28C

 

 Overview


In the commercial hot-water world, the 28c Series may be the only tankless solution you will ever need to know. With the 28c as your platform, you can solve the needs of a small restaurant kitchen, a school shower facility, or a large National Guard training base. The 28c can be used standalone, or it can be configured into multi-unit systems of 2 to 20 units controlled with Paloma's Manifold Electronic Controller.
