The ST215 is a small easy to use ergonomically designed controller in a hand-held case with rubber hand grips.† It is supplied with a wall mounting holster bracket and a flexible lead and plug as standard.† Bright orange LED displays are fitted.† The ST215 is designed to control single zone electric kilns and is derived from†the long established ST315 controller.
It is suitable for worldwide use with a universal power supply and selectable ∞C/∞F operation.
For a traditional pottery firing controller please see our ST216 (separate datasheet).† This is in the same product range as the ST215 controller and has 80 programs.

The ST215 is a 10-program controller designed for glass, ceramics & pottery use.† Each program can have up to 16 segments. It is fully adjustable with a detailed 4-lamp mimic display & continuous display of segment number.† Each segment comprises of a ramp followed by a soak.† Ramps can be heating or cooling.† It executes a controlled ramp to the soak temperature where it dwells for the required period then executes the next segment.† The end of the program is marked by selecting ‘End’ while entering a ramp rate.† Natural cooling then follows. Press the† key to display the program number – this can be changed if required with the† &† keys. To change any of the controller’s settings press the† key (or reverse with the† key) until the required lamp on the mimic display flashes.† The current value will be displayed together with a temperature, ramp rate or time icon.† Change the displayed settings with the† &† keys which can be held down for acceleration.† All settings are remembered while the controller is powered off.† The keyboard can be locked to prevent tampering.
The n key is used to commence a firing.† An optional start delay can be entered.† The progress of the firing is shown on the mimic display.† If a start delay has been set then the delay time remaining will be displayed.† During firing the program settings can be reviewed and altered if required and the program can be paused/resumed or advanced to the next segment.† The current set-point and the current energy used can be viewed by pressing the† key at any time.† During soaking the soak time remaining and the soak temperature are alternately displayed.† In the event of a power failure the controller will intelligently re-commence firing when power returns.
