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. This will allow less cycling of
the boiler and a more efficient installation. The RS100 is designed to control a single circuit of
heating.
There are two basic applications for the RS100:
• In single zone systems, as a remote boiler display with influence from the room or area where the controller
is installed
• This can be done with only room influence and no outdoor reset influence
• Since the RS100 is constantly reporting room conditions to the boiler, the boiler can still modulate
effectively—constant outdoor temperature reporting is not needed for normal operation (it is still beneficial
for freeze protection)
• The RS100 should be installed in the coldest room
• In multiple zone systems, as a remote boiler display only with no room influence from the controller
• This can be done with or without the room temperature displayed
• This would be considered a 100% outdoor reset boiler where the pump runs continuously and the load is
based solely on the outside temperature
• The RS100 can be installed in any room in this application
