NOTE: (Spectra II™
Only) Connect only a low voltage device to the relay output. Maximum current rating of the relay contacts is two amperes.
CAUTION: (Spectra II™
Only) The maxi- mum output of AUX 2 is 150 mA. If you connect a device that draws more current, you could destroy the output transistor. The output is in- tended to drive logic circuits or

5.Heater/Fan - This is a factory connection for a heater on outdoor pendant models.
6.Alarm Inputs - (Spectra II™ Only) If you need alarm inputs, connect them. The maximum number of alarm inputs is seven. Refer to Figure 8 for a typical wiring example. Alarm inputs require a ground signal through a contact closure, such as a switch.
7.AUX 1 - (Spectra II™ Only) An AUX 1 command from the controller will activate the relay output. If you need the relay, wire it as required. Refer to Figure 8. The relay contacts are shown when AUX 1 is inactive. When an AUX 1 command is issued, the relay contacts will reverse and remain latched until a clear command is issued.
8.AUX 2 - (Spectra II™ Only) An AUX 2 command from the controller will place a ground at the output of AUX 2 to operate the device connected to it. The output will remain latched until a clear command is issued. If you need the AUX 2 output, wire it as required. Refer to Figure 8 for typical wiring examples. The AUX 2 output is an open collector transistor driver that can pass a maximum of 150 mA at 32 VDC. It is capable of driving TTL logic circuits or
