OPERATION Initial Setup Instructions (Performed by Installer) NOTE: After installation, the installer should perform the following procedures to ensure proper operation of the heater. 1. Turn Unit ON: When the heater is first powered up the buzzer beeps for one second and displays all icons in high luminance and ON/OFF icon in half blue luminance for 3 seconds, then the unit will go to Stand-by Mode. In this mode only the ON/OFF icon illuminates in orange color in half luminance and all other icons will be OFF. On Standby mode, when the ON/OFF button is touched, all 4 buttons will illuminate a bright blue color indicating the heater is ON and the display board is powered up. Figure 5- Installation of Heater Assembly
2. Modes of Operation: The heater has five modes of operation. Heat Mode, Ventilation Mode, Lockout Mode, Centigrade or Fahrenheit Mode, and Volume Adjustment Mode.
Wiring of Heater
3. Heat Mode: When the power icon is ON, the first time you touch the Mode button the unit will go to the HEAT Mode. The screen is activated (heat icon blinking) and you can set the set point temperature (blinking) by raising or decreasing to your desired set point temperature. Touch mode button again to lock the desired temperature in place. Or, wait 30 seconds and it will lock in place automatically. If the screen is in the activated state, and there isn’t any button pressed in 30 seconds the display illumination is cut in half.

10.BMS (Building Management System): This feature is for optional use by building management systems. A red jumper wire connecting terminal A and B on the electronic power board can be removed and replaced by a Building Management System Switch. DO NOT REMOVE THE RED JUMPER UNLESS CONTROL BY A BUILDING MANAGEMENT SYSTEM IS BEING USED. A remote “dry contact” switch connected to terminals A-B on the control power board enables or disables control of the heater. Only a “dry contact” is required since it will not carry any load. This contact if “open” puts the heater in a standby “BMS” mode and it cannot be operated at the heater. When the heater is in the standby “BMS” mode, the element and fan is not operable and only displays the ambient temperature. BMS ICON (RED) will blink, (1) one second ON, (2) two seconds OFF. All other icons are turned off, and all buttons are disabled. When the remote dry contact is “closed” the heater returns to normal operation and all touch button functions are available at the heater. With nobody to control the heater functions at the heater location, the next ON cycle for the heater (when the BMS dry contact is closed) the heater automatically defaults back to the last setting prior to the time when the Red jumper was removed from the terminal block or when the dry contact was last opened. The desired set point temperature of the unit on BMS control should be adjusted and leave the unit powered up and not on Standby Mode before giving “automatic” heating control to the Building Management System.

THE ACTIVATION OF THE SAFETY LIMIT CONTROL AND RED WARNING LIGHT OCCURS WHEN THE HEATER OVERHEATS. CHECK HEATER TO MAKE SURE IT IS NOT BLOCKED – IF SO, REMOVE THE BLOCKAGE. IF THERE IS NO BLOCKAGE, IT IS RECOMMENDED THAT THE HEATER BE INSPECTED BY A REPUTABLE ELECTRICIAN OR REPAIR SERVICE TO ENSURE THE HEATER IS NOT DAMAGED. DO NOT CONTINUE TO USE HEATER IF IT REPEATEDLY CYCLES OFF ON THIS SAFETY LIMIT.
8. Failure Codes for Temperature Control Operation Display shows failure code: E1: Thermistor OPEN E2: Thermistor SHORT. If the heater is in working heat mode or vacation mode, and if there is a temperature sensor failure then the heater will stop working. It will provide 10 alert sounds and the failure code will blink continuously in bright blue light. The ON / OFF icon will be displayed in blue light. All other icons will be turned OFF and will not be displayed. Immediately turn heater OFF at the service panel. Investigate whether the thermistor cable is plugged in or not on the power board. If it is plugged in, check if it has opened or shorted. An open or shorted thermistor should be replaced. Call the factory for assistance or call a licensed electrician to inspect the heater.
