(Settings)
1. Setting the cooling or heating parameter P0 :-
The parameter P0 has two settings, C and H. When setting to C (default) the relay will energize when the temperature is reached. Use this setting if connecting to an air-conditioning system. When set to H the relay will de-energize when the temperature is reached. Use this setting if controlling a heating device.
2. 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 trigger temperature has been set to 25oC, it will not de-energize until the temperature falls back below 23oC. Setting this hysteresis helps stop the thermostat from continually triggering when the temperature drifts around the trip temperature.
3. 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.
4. 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.
5. 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.
6. Setting the trigger delay parameter P5
This parameter allows for delaying switching of the relay when the trigger temperature has been reached. The parameter can be set in one-minute increments up to a maximum of 10 minutes.
7. Setting the high-temperature alarm parameter P6
Setting a value for this parameter will cause the relay to switch off when the temperature reaches this setting. The seven segment display will also show ‘-‘ to indicate an alarm condition. The relay will not re-energize until the temperature falls below this value. The default setting is OFF.
