Start Up & Setting Operating Controls

Owner-Level Programming Instructions (Complete)

Covered within this section are features and settings typically accessed first by the installer, and then remaining accessible by the end user (the owner). These features reside at the Level-1 access point within the microprocessor. Note: if preferred, all programming may be performed without water flow, waiting to start the water pump as the last step in the set up and run process.

1.Applying Power to The Controller:

A.When power is first applied, the controller performs a lamp test and the display will read [888]. Following [888] the software version will display briefly.

B.The control will then display the actual water temperature, provided the circulating pump is operating, and adequate water is flowing through the heater.

C.If the pool-circulating pump is off, the control will display: [FLO]. This code message indicates no (or insufficient) water is being circulated through the heat pump.

2.MODE Controls Explained, and Starting the Heat Pump:

A.Once electrical power is supplied to the heat pump, sufficient water is circulating, and the heater controller has successfully completed its self-test, the heater is ready to operate.

B.The heat pump is shipped with the controller [MODE] function set to “OFF”. There are two ways to switch the heat pump OFF: First Method- One of the functions of the [MODE] button is “OFF”. Second Method- The thermostat set point can be lowered to a position below the minimum temperature setting (45oF); this action will cause the display to read “OFF”. To switch the unit ON, first use the mode button to select the HEAT mode—for Heat Only models—or, if the heat pump is a Heat and Cool model, use the mode button to select one of the following modes: HEAT, COOL, or ACH (Auto-Changer Over). In the [OFF] mode, the actual water temperature will be displayed as long as the circulating pump is operational and correct water flow is present. In the event water is not circulating through the heat pump (or flow is insufficient), the controller will display the [FLO] (No Water Flow) code message.

C.Using the UP ARROW key, increase the desired temperature until it exceeds the value of the actual temperature displayed. (Note: See # “8,” later in this section, if “000” is displayed upon pressing either the up or down arrow keys.) Once the desired temperature has been entered, the display will read the actual temperature and the heat pump will start to operate. Both the compressor and the fan must be operating before the “Heating” LED will illuminate. (Note: When MODE function is OFF, the current water temperature will be displayed; no functions, values, or programming will be available for adjustment.)

3.Turning The Heat Pump Off:

A.Method 1: using the [MODE] key, press the key until the display reads “OFF” The heater will shut off and remain off until the [MODE] key is used the select an operational mode. This is the preferred method for shutting off the heat pump.

B.Method 2: using the DOWN key, press the key until the desired water temperature reaches 45oF (minimum setting); then, press the DOWN key one more time, causing the display to read “OFF”. This method is typically used in conjunction with 2-wire external controllers; these controllers are equipped with their own thermostats.
