FRT535DW40BS is a complete pre-piped double wall instantaneous steam/water shell and tube heater. The assembly includes a 535 instantaneous Flo-Rite-Temp water heater with a Digital Recirculating Valve (DRV40) and BS - Connectivity Module.
Digital technology provides enhanced water temperature control accuracy and enhanced user safety in a single control component. BS - Connectivity Module technology to remotely view and adjust set point, datalog and monitor inlet hot, inlet cold/return and mixed water outlet with multiple BAS interface options.
- +/-2°F water temperature control at points of use 25 ’downstream during demand
- +/-2°F water temperature control during zero system demand “idling” periods
- 2°F minimum valve inlet to outlet temperature requirement (system recirculation temperature loss)
- Automatic shutoff of hot water flow upon cold water inlet supply failure
- Automatic shutoff of hot water flow in the event of a power failure
- Programmable set point range of 81-158°F (27-70°C)
- Programmable 1st level hi/lo temp alarm display
- Programmable temperature error level for double safety shutdown.
