Page 2 Installation: <Mounting the controller> 1. Make a 1.77 x 1.77" (45 x 45 mm) panel cutout (1/8" to 3/8" thickness) 2. Slide the controller into the cutout until the bezel is flush with the panel. 3. Slide the mounting bracket over the rear of the controller and press snugly against the rear of the panel.
Page 3 <Display and Buttons> 1. pH or ORP reading 2. Calibration mode 3. Calibration error indicator 4. HI relay energized LED indicator 5. LO relay energized LED indicator 6. Auto temperature compensation(ATC) or Manual temperature compensation(MTC) 7. Temperature reading and unit 8.
Page 4 Calibration: <pH> 1. Make sure the sensor is pH electrode and switch mode to pH mode. 2. Dip the electrode and the temperature probe into the buffer solution pH 7.00. Stir gently and wait until the reading is stable. Press and hold for 3 sec.
Page 5 HI, LO and Deadband Setpoints <HI and LO Relay> Relays switch state when their user-programmable setpoint is exceeded. They switch again when the limit is no longer exceeded. If the measurement exceeds the high setpoint, the high relay will switch state. If the measurement is lower than the low setpoint, the low relay will switch state.
Page 6 < Programming the Setpoints and the Deadband > 1. Press to choose pH or ORP mode. The controller will store the settings for pH and ORP separately. 2. Press and hold button until a beep sound, and then press to enter setting mode.
Page 7 Other settings <Back light> 1. Press and hold until a beep sound, release and then press and hold again. 2. Press to choose On, OFF, and Auto: On: back light is always on.
