M. 0-10 VOLT INPUT

1. A signal from a building management system may be connected to the appliance to enable remote control. This signal should be a 0-

10 volt positive-going DC signal. When this input is enabled, a building control system can be used to control the set point temperature

of the appliance. The control interprets the 0-10 volt signal as follows; when the signal is between 0 and 1.5 volts, the appliance will be

in standby mode, not firing. When the signal rises above 1.5 volts, the appliance will ignite. As the signal continues to rise towards its

maximum of 10 volts, the appliance will increase in set point temperature.

2. Connect a building management system or other auxiliary control signal to the terminals marked for this purpose on the appliance

terminal block (shown in Piping Diagrams, this manual). Caution should be used to ensure that the 0-10 VOLT + connection does not

become connected to ground.

NOTE: Ensure that the polarity of the connections from the external modulating appliance controller to the appliance is correct.

Reversed polarity could lead to erratic and/or no response from the appliance controller.

NOTE: Outdoor Temperature Mode Icon on the display will flash if an Outdoor Sensor or 0-10 Volt is not connected to the appliance.
