Page 11: Operation
BULLDOG Horizontal SpaceKeeper – Installation Operation Maintenance Manual OPERATION CAUTION: To avoid fouled machinery, extensive unit clean up, and void warranty, do not operate units without air filters in place, and do not operate units during the construction process. The BULLDOG Heat Pump provides year round cooling and heating as controlled by the unit thermostat or by a direct digital controller.
Page 12 BULLDOG Horizontal SpaceKeeper – Installation Operation Maintenance Manual COOLING OPERATION: Each heat pump has a water-cooled refrigeration circuit that operates only during the cooling mode. To enable cooling operation, MCO thermostats must be set to “Cool” mode. The ACO thermostats should be set to “Auto” or cool mode. In order for the cooling operation to become activated, the suite temperature must rise above the cool set-point temperature.
Page 13 BULLDOG Horizontal SpaceKeeper – Installation Operation Maintenance Manual RECOMMENDATIONS: 1. Set the thermostat fan to ON for continuous fan operation while your suite is occupied. This will help to ensure that the temperature is uniform throughout the suite. 2. In order to provide space conditioning while you are away, keep the thermostat system switch in the appropriate heat or cool mode.

Page 16 BULLDOG Horizontal SpaceKeeper – Installation Operation Maintenance Manual FAN OPERATION 1. A call on “G” for fan on the thermostat terminal strip will cause the fan to operate continuously on low fan speed through K5 on multi speed units. 2. A call on “W” for heat on the thermostat terminal strip will also cause the fan to operate on low speed.

Low pressure switch opens at 60 ± 3 psi and closes at 90 ± 3 psi. e. Air temperature sensor Ta – Sensor Ta will prevent compressor start-up if the air flowing through the unit is below 55F.
Page 18 BULLDOG Horizontal SpaceKeeper – Installation Operation Maintenance Manual hours will put the refrigeration system into a full and hard lockout, requiring a power down to reset. If two or less switch open shutdowns occur within a 24 hour period, they will be erased from memory and will not contribute to a future hard lockout.
Page 19 BULLDOG Horizontal SpaceKeeper – Installation Operation Maintenance Manual NOTE: The last flash code will be maintained in memory for one week or until the unit controls are powered down. The flash code will continue until the problem has cleared and the compressor has been put into operation.
Page 20 BULLDOG Horizontal SpaceKeeper – Installation Operation Maintenance Manual SHUTDOWN OUTPUT The CGC board has an optional input terminal strip that allows for two types of remote shutdown. These are a) compressor shutdown and b) unit shutdown. The advantage of these inputs is that many units can be connected in parallel and when powered by an independent 24V AC signal, one or both of these actions can be implemented.
Page 21 BULLDOG Horizontal SpaceKeeper – Installation Operation Maintenance Manual ALTERNATE FUNCTIONS Dehumidification cycle – When provided with an appropriate thermostat/humidistat, as well as dehumidification software and additional components, the CGC unit will provide space dehumidification. This is an optional feature. Two compressor units – All units larger than 5 tons include single speed belt drive fans. These twin compressor units are controlled individually through on board relays K4 and K6 (this is a specially programmed board that uses relay K6 to activate the second compressor, rather than it being used to activate high fan speed).
