Controllers. Each Temperature Controller can be individually programmed. Up to four universal can be fitted with Rinnai water heaters. Universal Controllers allow temperature selection only and one comes as standard with the water heater. Deluxe Temperature Controllers are available as an optional extra. - Page 10 TEMPERATURE CONTROLS Remote temperature controllers provide control over the water temperature. Rinnai water heaters can be operated with 1, 2, 3, 4 or no temperature controllers. Each time a button is pressed, a BEEP will sound. The BEEP sound can be muted by depressing the Temperature Controller Up and Down buttons simultaneously for more than 3 seconds.
- Page 11 The Digital Monitor will go out. If hot water taps are opened when the Rinnai is off, cold water will flow from the taps. If the system is to be left off over the winter be sure to drain it down if there is a possibility of freezing temperatures.

Page 14: Error Messages
ERROR MESSAGES Rinnai water heaters have the ability to check their own operation continuously. If a fault occurs, an error code will flash on the digital display (and on the Status Monitor) if you have temperature controllers installed. This assists with diagnosing the fault, and may enable you to overcome a problem without a service call. -

Page 22: Main Components
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. -
Page 23: Installation Instructions
Rinnai can not be held responsible for any consequential water damage so it may be necessary to fit a drain pan under the unit. - Page 24 See the pressure chart on page 48. Contact Rinnai or your supplier for 'gravity fed' or 'low pressure' hot water installations. Water pipe sizing and layout should be designed correctly to ensure the given water flows from the appliance are available.

Page 30: Temperature Controls
TEMPERATURE CONTROLS General Information Commercial installations do not generally have controllers installed. These installations usually have one permanent set temperature that is constant at all times. The public should not have access to alter the temperature in these situations. These installations do not require controllers as the temperature can be set by a series of dip switches on the PCB. - Page 31 TEMPERATURE CONTROLS Universal temperature controller - MC-91 1. Determine the most suitable position for the temperature controller. 2. Drill 3 holes in the wall (Fig.1), one for the cable and two for the securing screws. Fit wall plugs if needed and ensure controller is level. 3.
