Economizer Operation, Daylight Savings Time

5.3.6.1 ECONOMIZER OPERATION

If the air-conditioners controlled by the TCS do not have economizers, economizer operation should be disabled. This disables two stages of cooling that are normally used to energize the economizers if free cooling is available. Factory default for this value is enabled.

5.3.6.2 FREE COOLING ENTHALPY CHANGEOVER

The economizer changeover scheme is selectable between enthalpy changeover or dry bulb temperature changeover. The default for this is enable. When economizers are used the economizers will be used as 1st and 2nd stage cooling as long as the outdoor enthalpy is below the Enthalpy changeover setpoint. If the changeover scheme has been changed to dry bulb temperature changeover and you wish to change it back to enthalpy changeover use this item.

5.3.6.3 DRY BULB TEMPERATURE CHANGEOVER

The economizer changeover scheme is selectable between enthalpy changeover or dry bulb temperature changeover. The default dry bulb temperature changeover is disabled. If you wish to change the economizer changeover scheme to dry bulb temperature changeover use this item. When economizers are used the economizers will be used as 1st and 2nd stage cooling as long as the outdoor temperature is below the dry bulb temperature changeover setpoint.

5.3.6.4 DAYLIGHT SAVINGS TIME

If the area of the country where the TCS22 is located uses Daylight Savings Time, daylight savings time should be enabled for accurate clock readings. Factory default for this value is enabled.

5.3.6.5 50HZ CLOCK

If the area of the country where the TCS22 is located uses 50 HZ power, 50 HZ Clock should be enabled for accurate clock readings. Factory default for this value is disabled.

5.3.6.6 ZONE HUMIDITY SENSOR

The TCS can be ordered without an indoor humidity sensor. The model number will have a “T” in the 7th position of the model number if no humidity sensor was ordered. Factory default for this value is enabled. If the TCS does not have an indoor humidity sensor disable this feature.

5.3.6.7 Zone Dehumidification

The TCS22 can provide zone dehumidification by running the air conditioners and cycling electric heat on and off to maintain room temperature. Factory default for this value is disabled. Enable this feature if dehumidification is required. Note: The air-conditioner circuit breakers and wiring must be sized for concurrent operations air-conditioning and electric heat. Special dehumidification models are available for use with this feature. These models have circuit breakers and special MCA and MOP ratings that allow concurrent operation of the air conditioners and electric heat. These are special, dedicated code models ending in D053, D061, D062, D064, or D066. Consult your Bard representative for more information.
