EconoMi$er IV

Table 15 provides a summary of EconoMi$er IV. Troubleshooting instructions are enclosed.

A functional view of the EconoMi$er is shown in Fig. 43. Typical settings, sensor ranges, and jumper positions are also shown. An EconoMi$er IV simulator program is available from Bryant to help with EconoMi$er IV training and troubleshooting.

EconoMi$er IV Standard Sensors

Outdoor Air Temperature (OAT) Sensor

The outdoor air temperature sensor (HH57AC074) is a 10 to 20 mA device used to measure the outdoor-air temperature. The outdoor-air temperature is used to determine when the EconoMi$er IV can be used for free cooling. The sensor is factory-installed on the EconoMi$er IV in the outdoor airstream. (See Fig. 44.) The operating range of temperature measurement is 40_ to 100_F (4_ to 38_C).

Supply Air Temperature (SAT) Sensor

The supply air temperature sensor is a 3 K thermistor located at the inlet of the indoor fan. (See Fig. 44.) This sensor is factory installed. The operating range of temperature measurement is 0° to 158_F (-18_to 70_C). See Table 16 for sensor temperature/resistance values.
