Features and Benefits 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 Operation is controlled by simple rotary push button technology Digital display (with backlight): • Fahrenheit or Celsius • Ability to display outdoor temperature • Ability to display supply temperature • Ability to display sy
Scope of Use 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.
Scope of UseSingle 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. If the RS100 is not placed in the coldest room there is a chance that the room will not receive enough heat and therefore not be comfortable. The RS100 needs no additional installer level programming to work for this installation.
Scope of UseMultiple Zone System (Outdoor Reset mode) If multiple zones are used, it is likely not beneficial to have a single zone controlling the boiler’s demand. The RS100 can be used where its room information does not influence the boiler’s demand. Its clock functions are still active as well as the ability to adjust a theoretical temperature for comfort.
Scope of UseMultiple Zone System (Outdoor Reset mode) Outdoor Sensor Zone Pump Piping Zone Thermostats Third Party Controller The boiler in this application is operating with constant circulation and no input from room thermostats (on/off) or third party controls. The third party control panel cannot be connected to the boiler with an RS100 also connected. Boiler thermostat terminals 22 and 23 are inactive when the RS100 is connected. www.rinnai.

RS100 Operational Modes This allows selection of unique operational modes-a cursor is displayed above the selected mode. Any unique operating mode and its settings will be cancelled when a new unique mode is selected. Vacation mode-Heating will be inactive until the specified date (this example is September 24).At 0:00 (midnight) on this date, operation will resume. This can be set 250 days in advance. DHW operation is set to freeze protection (100°F default).
RS100 Operational Modes This allows selection of unique operational modes-a cursor is displayed above the selected mode. Any unique operating mode and its settings will be cancelled when a new unique mode is selected. DHW only will operate based on the times and temperatures set in the ―Timeprograms‖ chapter. If P1-P3 is selected, there will be up to three different schedules to choose. In this mode, heating will not operate—frost protection is enabled.
RS100 User Buttons Outdoor reset curve adjustment (K-Factor) 212 Default setting is 1.50 NOTE: If set to RC mode, adjusting this value will not have any effect on the controller or boiler. Example: If outdoor design temp is 14°F and max boiler supply is set to 122°F (perhaps for in-floor heating), a value of 1.00 should be entered here. 176 Boiler Temperature (F) This button adjusts the relation of boiler temperature to outside temperature.
RS100 User Buttons Information display Briefly pressing this button displays the following information (turning the dial clockwise will advance to the next reading): • Outside—displays current outside temperature reading from the outdoor reset sensor • Pressing the dial will show the average temperature over the last 24 hour period • Out.

Troubleshooting • When troubleshooting with an RS100, consider the following: • Jumping the thermostat terminals (22 and 23) to force the boiler to fire will do nothing unless the RS100 is disconnected from 20 and 21 • If the RS100 is not set for RC, the room conditions will not influence the boiler • If the RS100 is set for RC, outside temperature will not influence the boiler except for freezing or summer setback conditions • If max temp at the boiler is lower than the max temp at the RS100, the boiler’s
