The control shall lock on the Fan if the high temperature limit trips three times in one hour of operation.

The control will have a software programmable Fan Mode Switch for Auto operation or Continuous operation.

When the Fan is in the Continuous mode, it will run continu- ously during the occupied schedule and in the Auto mode when in an unoccupied schedule.

The control shall be capable of operating the fan without a G or fan signal from the thermostat.

EQUIPMENT CONTROL FEATURES

The control shall be capable of communicating on the Stan- dard Open protocol, Modbus® RTU.

The register data for the Modbus® must be publicly available and open.

Monitoring Software shall be provided at no cost. The moni- toring software shall have a flashing icon when any unit wired to the computer has an alarm. Clicking the flashing icon shall display the fault code and the details of the fault.

The networking setup shall be completed by connecting a three-wire daisy chain cable to each unit, then powering all the units up and pushing a button on each control. There shall not be any dipswitches to configure the network address.

The control shall use a communication driver that is capable of having 64 nodes on the bus before a repeater is needed.

The control shall use non-volatile memory to store the last five alarms. There shall be a single button to push to recall these last five alarms. The alarms shall be stored first in last out. The first flash code shall be the last alarm that occurred. There shall be a button press sequence to clear the alarms in non-volatile memory.

The control shall have a button to reset compressor lockouts without powering the unit down.

The control shall have a button to clear compressor Anti- Short Cycle Delays. When this button is pressed it will only clear the Anti-Short Cycle Delays for one cycle only and not permanently.

The control will be compatible with any BAS (Building Auto- mation System). Any BAS shall be able to control the equip- ment when wired to the control's Thermostat Terminal Strip.

The control shall have loading of at least 25 milliamps on all thermostat inputs for controllers and thermostats that use out- put TRIACs.

The control shall have a Smoke Detector Shutdown input on the board. The control shall be powered through this input, so when the Smoke Detector trips, the control will shut down the unit immediately.

The control will have low voltage protection for the contactors and will not energize a contactor if the voltage is below 19.2 VAC, to insure contactor pull-in. If the control has a compres- sor contactor energized when the voltage drops, it shall not de-energize the contactor until the voltage drops below 16 VAC, which is the drop out voltage for most contactors.

The control shall have a means of low ambient control with- out adding any additional components. The control shall have a means of cycling the compressor on for 10 minutes and off for 5 minutes to defrost the indoor coil when the out side ambient is below a low ambient switch point without add- ing additional components.

The control shall have a means of storing compressor run time. This data shall be available through communication. The control shall have the ability to clear this data when a compressor is replaced.

The control shall have the ability to store a name of at least 26 characters in length. The control will leave the factory with the serial number of the equipment it is in, stored in non-vola- tile memory in the Name location.

The control shall have the ability to store the model number of the equipment of at least 26 characters in length. The con- trol will leave the factory with the model number of the equip- ment it is in, stored in non-volatile memory.

The control shall have the ability to store the serial number of the equipment of at least 26 characters in length. The control will leave the factory with the serial number of the equipment it is in, stored in non-volatile memory.

The control shall not power the contactors through the ther- mostat wiring. Dropping voltage over the thermostat wiring causes chattering contactors when the contactors are pow- ered in this manner.

The control will operate and monitor up to 3 stages of heat independently.

The control shall monitor the Gas Heat operation in the heat- ing mode. It shall monitor the gas valve when there is a call for heating. The control shall alarm when there is a call for heat and no gas valve voltage after 5 minutes.

There will only be one control board for this series of units, for both CV and VAV operation.

COMFORT CONTROL FEATURES

The control will be installed and tested at the factory where the equipment is assembled.

The control will use a Wall Senor that has a means of overrid- ing the unoccupied mode for a programmable amount of time.

The Unoccupied Override time will be programmed in min- utes up to 4 hours.
