Setting the trigger temperature:

To set the trigger temperature press the button marked 'SET'. The seven segment display will flash.

You can now set a trigger temperature (in oC) using the '+' and '-' buttons in 0.1 degree increments. If

no buttons are pressed for approximately 2 seconds the trigger temperature will be stored and the

display will return back to the current temperature.

Setting the parameters:

To set any parameter first long press the 'SET' button for at least 5 seconds. The seven segment

display should now display 'P0'. This represents parameter P0. Pressing the '+' or '-' buttons will cycle

though the various parameters (P0 to P6). Pressing the 'SET' button whilst any of there parameters

are displayed will allow you to change the value for that parameter using the '+' and '-' buttons (see

below). When finished setting a parameter press the set button to exit that option. If no buttons are

pressed for approximately 5 seconds the thermostat will exit the parameter options and will return

back to the default temperature display.

Setting the cooling or heating parameter P0:

The parameter P0 has two settings, C and H. When set to C (default) the relay will energise when the

temperature is reached. Use this setting if connecting to an air-conditioning system. When set to H

the relay will de-energise when the temperature is reached. Use this setting if controlling a heating

device.

Setting the hysteresis parameter P1:

This sets how much change in temperature must occur before the relay will change state. For

example if set to the default 2oC and the the trigger temperature has been set to 25oC, it will not de-

energise until the temperature falls back below below 23oC. Setting this hysteresis helps stop the

thermostat from continually triggering when the temperature drifts around the trip temperature.

Setting the upper limit of the thermostat parameter P2:

This parameter limits the maximum trigger temperature that can be set. It can be used as a safety to

stop an excessively high trigger temperature from accidentally being set by the user.

Setting the lower limit of the thermostat parameter P3:

This parameter limits the minimum trigger temperature that can be set. It can be used as a safety to

stop an excessively low trigger temperature from accidentally being set by the user.

Setting temperature offset correction parameter P4:

Should you find there is a difference between the displayed temperature and the actual temperature

(for instance if the temperature probe is on a long run of cable) you can make minor corrections to

the temperature reading with this parameter.

Setting the trigger delay parameter P5:

This parameter allows for delaying switching of the relay when the trigger temperature has be

reached. The parameter can be set in one minute increments up to a maximum of 10 minutes.

Setting the high temperature alarm parameter P6:

Setting a value for this parameter will cause the relay to switch off when the the temperature

reaches this setting. The seven segment display will also show '---' to indicate an alarm condition. The

relay will not re-energise until the temperature falls below this value. The default setting is OFF.
