NOTE: With this type of two-wire remote, with its own temperature sensors and system control, using the up arrows on the front of the DDTC, hold down the up arrow until you reach the maximum setting of 104° F., this allows the remote system thermostat to operate the heater at any set-point below 104° F., the heater thermostats then act as a secondary controller if water temperature reaches 104° F.
THE THREE-WIRE REMOTE CONTROL SYSTEM will be connected to terminals J5, J6 & J8.
J8 is the common terminal. If the heater is in the REMOTE mode, the DDTC will monitor the terminals and respond to a contact closure between J5 & J8 or J6 & J8. A contact closure between J5 & J8 will cause the DDTC to switch to the POOL setting and control the heater to the DDTC pool set-point temperature. A contact closure between J6 & J8 will cause the DDTC to switch to the SPA setting and control the heater to the DDTC spa set-point temperature. If only heating the spa, then depress the pool down arrow until the display goes to “Off”.
SECTION IX. TROUBLE SHOOTING
The DDTC temperature display contains three LED’s with a decimal point between the first and second, this display is also used to display an error code if for some reason there is a failure within the heater control system or a DDTC internal fault. The DDTC will display the actual temperature or set-point temperature or OFF, as selected by the user. When DDTC detects an error, the display will show Exx, see Figure 8, where Exx is the error code of DDTC fault, see Table 1. Codes 1 through 9 indicate a “soft lockout” error that means after these errors are fixed, the heater will resume normal operation and restart immediately. Code ERR indicates a “hard lockout” error that means after these errors are fixed, you need to reset the power of the heater through the switch on the bottom of the electrical junction box on the right side of the cabinet.
NOTE: If Code ERR is shown on the LED display at any time, turn the heater off, (from power switch), then turn on the heater again. If the error code is still displayed, call a certified Pentair Service Technician for repair.
