Locking and Limiting
- The RET2000 has an Advance Programming Mode in order to set up temperature lock and limit settings.
- Press the V button when in heat mode or Λ button when in cool mode until the standby mode is reached.
- The Λ button or V button should then be released and then pressed and held for a further 5 seconds to enter the Advanced Programming Mode.
- To indicate that the unit is in Advanced Programming Mode the Standby Indicator will flash and the display will show the setting number alternating with the current value for that setting.
- To change the setting press either the Λ or V button.
- A simultaneous push and release of both buttons will scroll through the steps S1 to S3 and will save the current set value if altered.
- To exit Advanced Programming Mode and return to Standby Mode press and hold both buttons for more than 5 seconds.
- While in Advanced Programming Mode if no buttons are pressed for more than 2 minutes the unit will automatically return to Standby mode, and the value on the current setting will not be saved.• A simultaneous push and release of both buttons will scroll through the steps S1 to S3 and will save the current set value if altered.
- To exit Advanced Programming Mode and return to Standby Mode press and hold both buttons for more than 5 seconds.

S1 – Lower Temperature Limit
- This setting allows for a Lower Temperature Limit to be set. The Lower Limit can be set between 5°C (41°F) and 30°C (86°F) in Heat mode, or between 16°C (61°F) and 36°C (97°F) in Cool mode.
- Default – 5°C/41°F for Heat mode or 16°C/61°F for Cool mode.
S2 – Upper Temperature Limit
- This setting allows for a Upper Temperature Limit to be set. The Upper Limit can be set between 5°C (41°F) and 30°C (86°F) in Heat mode, or between 16°C (61°F) and 36°C (97°F) in Cool mode. However, this will be limited by the Lower Temperature Limit set in S1 therefore the Upper Temperature Limit cannot be less than the Lower Temperature Limit.
- Default – 30°C/86°F for Heat mode or 36°C/97°F for Cool mode.
S3 – Set Point Power-Up Temperature
- This setting defines the set point at power up when Button Lock is enabled on the DIL switch.
- This can be set between the Lower and Upper Temperature Limits set in S1 and S2.
- Default – 21°C/70°F for Heat mode or 24°C/75°F for Cool mode.
