Additionally there is a momentary-contact button to energise a second relay that is enabled when the controller output is latched. This has been used for the purpose of, for instance, engaging the starter motor on a generator.once the generator is enabled by the main relay.
Switching According to Temperature
When the controller detects that an optional digital thermometer is connected it will automatically start switching the main output relay according to the temperature input and the preset upper and lower limits.
The upper and lower temperature thresholds are easily set on the mobile phone and transmitted to the remote controller for storage in its non-volatile memory. Values between -55 and 128 deg. C are valid. The unit can be programmed for either heating or cooling - when in cooling mode it will switch on when the upper limit is reached and remain so to the lower limit, when heating it will switch on at the lower limit and maintain that state until the upper threshold is reached.
In both modes the output will switch off if contact with the thermal probe is lost. Temperature control takes precedence over manual control and other modes are disabled as long as the presence of the digital thermometer is detected.
Switching Controlled by Timer
There is a faciltiy to program an 'On' time followed by an 'Off' time that the Remote Control will follow whether connected to the mobile or not. Both intervals are specified in seconds from 1 to 1 million. The manual 'On' control will override the timer. When manual control is reliquished the automatic timer will resume functioning as before.
To programme the timers the Remote Control must be BT connected to the mobile with Buttons Disabled. Tap the DactylTech logo 3 or more times in quick succession and the screen at right will appear. Edit the ON and OFF times (in seconds) and tap Send. The values are saved in non-volatile memory in the Remote Control. Timer control carries the lowest precedence, behind Temperature and Manual.
