Simply pressing and holding this button for 6 seconds will activate the self-test sequence as shown in the chart below. During this test, the installer or technician may observe the air-conditioner for the expected function and duration, indicating that all are operating properly. On completion of the self-test, the air-conditioner automatically returns to normal running condition. The control board is also outfitted with an Infrared LED diagnostic port. Optional software and an infrared / RS232 Interface cable are available from Dantherm, enabling the unit to be connected to a portable laptop computer. In this manner, comprehensive and detailed real-time operational data may be observed, diagnostics run, and data imported onto the laptop. Call for more details.

Dantherm CLASSIC 20 Air-Conditioner Alarm Capabilities All Dantherm Classic units have built-in alarm capabilities programmed into the control board. Failure Modes The following conditions will activate the failure alarm output on terminals 7 and 8: Loss of supply voltage Low Pressure (< 10 psi for 300 seconds) High Pressure (> 400 / 500 psi) Low or no current to compressor (less than 1 amp) High Return Air Temperature (18 o F / 10 o C higher than cooling set point) Low Return Air Temperature (9 o F / 5 o C lower than heater set point) Alarm Connections The alarm cable consists of four wires: Black wire: connected to terminal 7 on the control board Red wire: connected to terminal 8 on the control board White wire: not used Green wire: not used Alarm Description Only the red and black wires are used and are connected to terminals 7 and 8 of the control board. Terminals 7 and 8 operate as a normally closed contactor and open upon failure. During normal operation, a relay is energized, providing continuity between terminals 7 and 8. When a failure is detected, the relay is deenergized such that there is no continuity between terminals 7 and 8. A low voltage signal (up to 50V DC and 0.1 amps) may be connected to the contactors for external alarm capabilities. Performance Curves 9
