Page 12: Electrical Connections
ELECTRICAL CONNECTIONS • Electrical wiring shall conform to the requirements of the authority having jurisdiction, or in the absence of such requirements, to the National Electrical Code ANSI/NFPA 70 (United States) or Canadian National Electrical Code CSA C22 (Canada). • Power supply is 115 volts, 60 hertz, single phase, less than 2 amps. -
Page 13: Operation And Use
OPERATION AND USE The DHW Module shall be piped to a boiler that incorporates a low limit control to maintain boiler water temperature. Limit settings may be varied to meet the requirements of the installation. The low limit setting shall be at least 10°F (5.5 °C) below the high limit setting for proper operation. - Page 14 Temperature Regulation The set point temperature T1 of the DHW fluid at the heat exchanger outlet is factory set to the default value of 122 °F (50°C). The REC is equipped with trimmer P1, accessible by removing the rubber plug located on the front cover, with which the temperature T1 can be adjusted to a value different from the factory setting.

Page 15: User Interface
USER INTERFACE The user interface integrated in the REC consists of the following devices: • LCD Display Shows programmed DHW set-point temperature T1 and fault codes. The display can be either degrees Fahrenheit (display shows three digits) or Celsius (display shows two digits). The factory setting is Fahrenheit. See Dip Switch section below (dip switch 4) to change display settings. - Page 16 • Dip Switches The dip switches are located on the control board inside the REC. The factory configuration is: switches 1-5 in the OFF position and switch 6 in the ON position. Switch 4 toggles the display between Fahrenheit and Celsius. All other switches must remain in their factory configuration.
- Page 17 Fault Codes The FAULT led indicates the following faults • Temperature Sensor T1 Fault, code 6 on the LCD display If the T1 sensor fails it immediately interrupts the domestic hot water supply. The fault is indicated by blinking FAULT led and shown on the LCD display with the blinking code 6. The normal operating condition is automatically enabled by restoring the correct functionality of the sensor.
