Description
The Mr. Steam MSTS is the remote temperature probe you need when your steam control is mounted outside the steam room. The probe goes inside the steam room and connects by cable directly to the steam generator's circuit board, so the generator reads the actual room temperature. It is for installs where the control sits in a hallway, dressing area or bathroom wall instead of inside the shower.

- Function: remote temperature sensing inside the steam room
