tekmar Control Systems introduces the tekmarNet Thermostat 557, 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 a backup heating system, or two stages of heating and two stages of cooling. Three auxiliary sensor inputs measure room, floor, outdoor or duct temperature. The optional floor sensor allows precise heating of radiant floors. The relative humidity level can be measured and controlled using either the built-in or external humidity sensor. www.tekmarcontrols.com/products/zoning/557.html
