Controlling the external fan by temperature triggered dry contact
The Temperature trigger has a user configurable range of +20°C to +55°C (68
– 131°F). When the battery
temperature (monitored by the battery temperature probe) reaches the high temperature threshold, the assigned
relay energizes and can be used to turn on the external fan. The relay is de-energized when the temperature
drops by 10ºC (18ºF). The default high temperature threshold is 55ºC (63ºF).
