RS100 –Programmable Wall Thermostat with room setback • The RS100 connects directly to the boiler and acts as a central thermostat for the entire structure • Direct communication with the boiler allows it to fire based on the area’s immediate needs •...
Applications for the RS100 Room controller The RS100 is a room controller and not an on/off room thermostat. It is intended to work only with Rinnai boilers. When used in conjunction with a Rinnai boiler it will sense the room temperature and use it to influence the supply water temperature.

Scope of Use- Single Zone System (RC mode) The RS100 can be used to control a single heating zone system. A single heating zone system has only one loop of heating. The placement of the RS100 is very important; it must be placed in the coldest room within the single zone system.

Controller theoretical temperature for comfort. In this application, the RS100 will allow the boiler to switch between day and night outdoor reset curves. The boiler is then operating with constant circulation and no input from room thermostats (on/off) or third party controls.
Electrical Connections Below is the connection for the RS100. Please refer to the installation manual and Rinnai’s recommended application guide for more details or contact Rinnai’s Engineering Department as needed Outdoor reset sensor (included with boiler) On/Off room Release the tab at connects here.
