Maximum Damper Position

Set the maximum EconoMi$er+ position. Normally this is set at 100%. If using 3-position control or there is a reason not to use 100% outside air, this can be set using the EconoMi$er+ Maximum Position (MAX_POS_SP).

Compressor Lockout Temperature

Set the Compressor Lockout Temperature. The Compressor Lockout Temperature (CMP_LOCK) is used to prevent com- pressor from running at low ambient conditions when an EconoMi$er+ can easily satisfy the load.

EconoMi$er+ Changeover Control

Determine the type of EconoMi$er+ changeover control which will be used to enable and disable free cooling. This is done using the EconoMi$er+ Changeover Type.

1.Switch — This changeover setting is used when a remote signal from an energy management system will enable and disable the EconoMi$er+. This is done through a remote EconoMi$er+ enable switch.

2.Outdoor Dry Bulb — For this changeover setting, the EconoMi$er+ will be enabled based on the outdoor-air temperature. The EconoMi$er+ is shipped with an outdoor air temperature sensor. The outdoor air tem- perature set point can be configured by the user. The EconoMi$er+ will be disabled when the outdoor-air temperature rises above the set point. The configura- tion variable is the EconoMi$er+ Changeover set point (OAT_SP).

3.Differential Dry Bulb — For this changeover setting, the EconoMi$er+ will be enabled whenever the out- side-air temperature is lower than the return-air temperature. No configuration of set points is required other than to select the differential dry bulb function.

4.Outdoor Enthalpy — For this changeover setting, the control will enable the EconoMi$er+ based on the outdoor-air enthalpy curves as shown in Fig. 29. Using the EconoMi$er+ Changeover set point (ENTHALPY_SP), select curves A, B, C or D. The control will then use the EconoMi$er+ at conditions below the curve. The control uses the OAT and optional humidity sensor to calculate the enthalpy and also has the A, B, C, and D curves stored in memory.

5.Differential Enthalpy — For this changeover setting, the EconoMi$er+ will be enabled based on the com- parison of the enthalpy of the return air and outside air. If the outside air enthalpy is lower than the return air, then the EconoMi$er+ will be enabled. To use this option, an accessory outside air humidity sensor, a return air dry bulb sensor and a return air humidity sensor must be ordered and installed. No configuration of set points is required other than to select the function.

C.Demand Ventilation Configuration

The EconoMi$er+ control has demand ventilation control capability when using an IAQ sensor. The indoor air quality (IAQ) is measured using a CO2 sensor. The IAQ sensor can be field-installed in the return duct or the occupied space.

The EconoMi$er+ control algorithm modulates the position of the EconoMi$er+ damper between two user configurations depending upon the relationship between the IAQ and the Outdoor Air Quality (OAQ). The lower of these two positions is referred to as the Minimum IAQ Minimum EconoMi$er+ Position (IAQMIN_SP).

The higher position is referred to as the Occupied EconoMi$er+ Minimum Position (ECONOMIN_SP). The IAQMIN_SP should be set to an EconoMi$er+ position that brings in enough fresh air to remove contaminants and CO2 generated by sources other than people. The ECONOMIN_SP should be set to an EconoMi$er+ position that brings in enough fresh air to remove contaminants and CO2 generated by all sources including peo- ple at the design value for maximum occupancy.

Areference differential CO2 level above the outside CO2 level is used as the starting point for IAQ control and another reference differential level for maximum ventilation at design occupancy is used for the end of IAQ control. Between these points the control will modulate the dampers open from the IAQMIN_SP and the ECONOMIN_SP set- points. The damper position will never go above ECONOMIN_SP or below IAQMIN_SP.

The control does not measure the outdoor IAQ reference level as these levels are relatively constant. The installer should take a measurement at start-up of the unit and enter this value into the control using the Outdoor Air IAQ refer- ence level configuration.

The control is configured for air quality sensors which pro- vide 4 mA at 0 ppm and 20 mA at 2000 ppm. If a sensor has a different range, these bounds must be reconfigured.

To configure the control for an IAQ sensor perform the fol- lowing steps:

1.Determine the Occupied EconoMi$er+ Minimum posi- tion (ECONOMIN_SP) and enter it into the control.

2.Determine the IAQ minimum EconoMi$er+ position (IAQMIN_SP) and enter it into the control.

3.Enable IAQ control using IAQ Enable (IAQ_FLG).

4.Determine the Outdoor Air IAQ Reference (OAQ) and enter it into the control.

NOTE: The value entered into the control will be the CO2 ppm level divided by 10. For example, 400 ppm would be entered as 40.

5.Determine the lower control point differential level (DAQLO) and enter it into the control. This is a dif- ferential level so if the desired level to start IAQ con- trol is 500 ppm and the OAQ reference level is 400 then a value of 100 would be used.

NOTE: The value entered into the control will be the CO2 ppm level divided by 10. For example 100 ppm would be entered as 10.

6.Determine the upper control point differential level (DAQHI) and enter it into the control. This is a differ- ential level so if the desired level to start IAQ control is 1100 ppm and the OAQ reference level is 400 then a value of 700 would be used.

NOTE: The value entered into the control will be the CO2 ppm level divided by 10. For example 700 ppm would be entered as 70.

D. Power Exhaust Configuration

The EconoMi$er+ can control up to 2 stages of power exhaust. Power exhaust activation is done through config- urable damper position set points. The first stage of power is controlled by relay C4 on the EconoMi$er+ board. The acti- vation point for the first stage is set using the Power Exhaust Stage 1 Activation set point (PE_SP1). The second stage of power exhaust must be set at a value greater than the first stage. It is configured using the Power Exhaust Stage 2 Activation set point (PE_SP2).
