Technical Data Job or Customer : Location : Engineer : Complies with Spec Alternate Notes : Contractor : Tamas Rep : Submitted By : Date : Approved By : Date : P.O. Number : Date : Description The Tamas Snowmelt Panel, in conjunction with the snowmelt control, socket, and sensor, utilizes optics rather than continuity based on/ off sensors. This method of snowmelt detection allows for great efficiencies and set point controllability. The control on the panel measures slab temperature, as well as boiler loop temperature to ensure the return water going back to the boiler does not shock the boiler heat exchanger. The snowmelt system pump is piped independently from the boiler loop so that the only head loss that needs to be calculated in the system is the piping from the panel to the manifold, and the loops in the slab. This feature allows for higher flow rates and head losses if needed, which in turn expands the range of pumping ability for the system pump.
