Operation Selecting the Temperature Unit (°C or °F) This thermostat features an adjustable display setting that can display the temperature in either Celsius or Fahrenheit. • To enter the setting mode, press the UP and DOWN buttons at the same time for 3 seconds. The screen will display CR (cycle rate) and a number on the bottom pane along with the Fahrenheit or Celsius temperature reading on the top pane. • Press the UP button to toggle between the °C or °F display.
Operation Selecting the Heat Cycle Rate . . . continued While it is still in the Setting mode, press the DOWN button to toggle between the various CYCLE RATES. There are 3 different cycle rates to choose from: Cr Cycle Rates Cr-0 OFF (fixed span) Cr-1 20 seconds Cr-2 240 seconds (4 minutes) Cr 0 is a fixed span (no cycling), with a variance of +/- 0.3°C (+/- 0.6°F). The heating unit will operate at full power and the power bar will appear full.
Operation Adjusting the Desired Set Temperature The current /room temperature (A) is normally displayed on the LCD screen. To adjust the setting to the desired set temperature, press the UP (C) or DOWN (B) button. • The temperature can be set in increments of 0.5°C or 0.5°F. • The temperature setting range is from 5°C to 35°C (41°F to 95°F.) A B C Tip: Press and hold the UP or DOWN button to change the setting more rapidly.
Operation Heating Power Level Display When the thermostat activates the heating system, the Heat “On” symbol will appear. Equipped with an intelligent proportional regulation system, this thermostat will determine the amount of power needed by the electric heater to maintain the room temperature at precisely the set temperature. The “Power Bar” (A) will indicate the current output power level.
Troubleshooting Problem Solution The LCD screen is blank or abnormal • • • The thermostat housing feels hot to the touch Make sure the thermostat is fully installed. Check that the power supply has been reconnected at the circuit breaker or fuse. If the heater or heating appliance has a power switch of its own, check to see that it is in the ON position. When working at full capacity, the thermostat housing may reach a temperature of approx. 45°C to 50°C (113°F to 122°F).
