2OACH SERIES Portable Air-Cooled Heat Pump 1

DELUXE ELECTRONIC CONTROLLER The 2OACH controller is equipped with many features for a more precise level of comfort and operation. Additionally, the controller can be removed from the unit and installed for remote operation, if needed (accessory parts may be required). POWER button OCEANAIRE DELUXE ELECTRONIC CONTROLLER When power is connected, the controller will display 888 momentarily, and will then disappear. Press the POWER button, then press the TEMP SELECT button until the SET POINT is displayed. Adjust the SET POINT to the desired temperature, and the unit will heat/cool as programmed. POWER The systems controls temperature within +/- 2 - Turns the unit on/off when power is supplied MODE - Select the mode of operation from AUTO...COOL.HEAT.MOISTURE CONTROL. AUTO - The controller will heat or cool as required. HEAT or COOL will display accordingly. A 4 differential is needed to change between cooling and heating modes. COOL - The system will operate in cooling mode, only. HEAT - The system will operate in heating mode, only. MOISTURE CONTROL - The system operates in the cooling mode to reduce humidity within the conditioned space. Every 4 hours, the fan is started, circulating the air, and the air temperature is recorded by the controller. The cooling cycle is started for one hour, or until the room temperature drops 2, which ever comes first. This cycle repeats every four hours. 2

FAN SPEED The operator can select between AUTO or MANUAL fan speed control. Pressing the FAN SPEED button will switch speed from AUTO to MANUAL. In MANUAL mode, pressing the FAN SPEED button will change fan speed from low to high. In AUTO mode, the fan speed is controlled automatically. In cooling mode, the controller automatically adjusts the fan speed to high, and as the inside temperature approaches the set point, the fan speed will reduce. In heat mode, the fan speed adjusts from low to high as the temperature reaches the set point TEMP SELECT Allows the operator to view the controller temperatures INSIDE = return air temperature, DISCHARGE = supply air temperature, SET POINT can be seen and adjusted by pressing or. CONTROLLER PROGRAMMING MENU 1) Make sure the unit has power. 2) Press the power button OFF. 3) Press the following buttons in sequence S-U-D-S (Select Up arrow Down arrow Select) 4) The display will begin flashing P1 and a number. If there is no display, repeat the sequence, making sure the unit has power, but is turned OFF. 5) To adjust any program feature, press the ARROW UP or ARROW DOWN button until the desired value is displayed. 6) Use the MODE button to scroll through the programmable settings P1 through P16. 7) If no buttons are pressed, the display will then return to the OFF position after about 50 seconds. PROGRAM SETTINGS P1 High Fan Speed Limit Setting. 56-85 P2 Low Fan Speed Limit Setting, 30-55 P4 Temperature Sensor Calibration, +/- 10 P10 Temperature Display, F or C P13 Supply Fan Operation, Cycling or Continuous P15 Fan Motor Type Setting, PSC or Shaded Pole P1, P2 - To adjust fan speed settings, P1 represents the high fan speed parameter, while P2 represents the low fan speed parameter. When using nozzle kits, discharge duct adapters and evaporator plenums, setting P1 to 85 will help to avoid freeze ups. P4 - Adjust the P4 setting to match the actual INSIDE room temperature, if needed. P10 - Use this parameter to display temperatures in the desired units. P13 - To cycle the evaporator fan with the compressor, access code P-13. Press the up or down button to switch to CYC, which means cycle the fan with the compressor. The factory default setting is CON, which means continuous fan operation. P15 - Fan Motors are PSC type, SC - should be selected. 8) Press POWER - you should see an alphanumeric code. Press POWER and the unit will start at the new settings. 3

THREE PHASE MONITOR Three-Phase units are equipped with monitors for motor protection. The OceanAire Three-phase Monitor safeguards the unit against incorrect compressor rotation, low-voltage and/or loss of power in any one of the power legs. The monitor is installed in the control box and is equipped with an LED for diagnosis of an improper electrical condition (see diagrams below). When power is connected, the compressor WILL NOT engage until the monitor start delay has timed out. If the thermostat does not power up, an electrical condition may need to be addressed. Remove the control box cover and observe the LED on the phase monitor. The LED signals the following: GREEN-BLINKING - Start delay, 120 sec. GREEN - Proper Operation RED/GREEN-BLINKING - signals reverse phase rotation. Switch any two of the power leads for the unit, NOT THE MONITOR LEADS, and re-start. RED-BLINKING - signals improper voltage and/or phase loss. Correct the power problem, then re-start the unit. In the event of a power interruption, the unit will re-set to a start-up condition. The Phase Monitor will not allow the unit to start until power is corrected. 55
