IMPORTANT INFORMATION Always check water temperature before Hot water may go cold without warning at use. very low water flows (less than 3 l/min.) Refer to warning about hot water on page 16 for important safety information. The Infinity 16i controls the water tem- If freezing temperatures perature automatically.
Turn On by opening the hot water tap COLD The Rinnai Infinity 16i water heater has a built in controller on the front cover for adjusting the temperature. Additional remote controllers are available to locate near the points of use, and give precise digital temperature control.
TEMPERATURE CONTROLS The purpose of a Temperature Controller is to enable the user to have complete control over the hot water supply. Used correctly, the Infinity will supply hot water at the temperature selected, even when the water flow is varied, or when more than one tap is used.

TEMPERATURE CONTROLS - OPERATING Remote temperature controllers are a feature that provides control over the water temperature. The Rinnai Infinity 16i water heater can be operated with 1, 2, or 3 temperature controllers. The controller MC-45-SR-EU comes as standard with this water heater installed into the front panel.

TEMPERATURE CONTROLS - OPERATING Using the Temperature Controllers. Press the ON/OFF button on a temperature controller. The system will become active, the temperature will default to 40 C and the controller that turned the system on will have priority. The temperature setting on the controller will light up.

OPERATION PRINCIPLE HOT WATER SUPPLY OPERATION Ignition Press ON/OFF Button of Remote Controller to turn on unit and the remote control- ler display and priority LED will light up. When a hot water tap is opened the Water Flow Sensor revolves and sends a pulse signal to the Printed Circuit Board (PCB.) When the PCB detects water flow it be- gins the ignition process with the Combustion Fan Motor starting first.
MAIN COMPONENTS 1. Gas Control Unit 1.1 Modulating Valve This device is used by the PCB to adjust the volume of gas to the burner in proportion to the volumetric flow rate of water in order to maintain a supply of constant temperature hot water amid changes in water flow rates and incoming temperatures.
