511 Programmable Thermostat
The Programmable Thermostat 511 is a microprocessor based control designed to operate mechanical equipment to deliver heat to a single zone within a hydronic heating system. It can be used with any terminal unit type, including radiant floor, baseboard, and fan coils. This product maintains very accurate and even air temperature with Pulse Width Modulation and Auto Heating Cycling. It is capable of controlling a zone valve or zone pump directly or through a tekmarNet (R) 4 Wiring Center or Zone Manager to maintain air temperature and 2 auxiliary temperatures. These temperatures could be floor or remote air. An optional Adaptor Plate 007 is available which allows the thermostat to be installed onto a single gang electrical box.
