tekmarNet 4 Thermostat - Two Stage Heat, Two Stage Cool, Two Fan

The tekmarNet Thermostat 557 is a communicating touchscreen thermostat designed to operate either: a hydronic radiant floor with a two stage heat pump (water-to-air or air-to-air) for heating & cooling and an emergency backup heating system; or two stages of heating and two stages of cooling. There are three auxiliary sensor inputs that can be used to measure room, floor, outdoor or duct temperature. The optional floor sensor allows precise heating of radiant floors. Relative humidity level can be measured and controlled using either the built-in or external humidity sensor. The large touchscreen display allows you to easily adjust 7-day programmable schedules and room temperatures to optimize comfort and energy savings. The 557 can connect to tekmarNet controls using two or four wires or it can operate as a stand-alone device. 3 Auxiliary Sensor Inputs Air Group Master Auto Heating Cycle Away Scene Key Backlight Daylight Savings Time Exercising Freeze Protection Heat / Cool Priority Network Schedule Master or Member Optimum Start Outdoor & Floor Temperature Display Programmable Schedule Radiant Floor Heating & Cooling Relative Humidity Control Room Temperature Limiting Scenes Temporary Hold Touchscreen Technology Warm Weather Shut Down Zone Post Purge Zone Synchronization tekmarNet® Communication Compatible
