EK186 Multi-Range Thermostat
Product Presentation
1. Selection of the range
2. Adjustment of the temperature setting
3. Selection of temperature range
4. Display of state of output
Working Principle
the EK186 regulates the temperature according to all or nothing
principle, it can be associated with different probes, according to the
application the accuracy is a function of the temperature
range and is selected by a slide switch.

- Preferential accuracies for each temperature range.
Example of Choice of Accuracy
• Regulation of ambient temperature
Range: 0 to +30ºC
Accuracy: ± 0.18ºC = 2
• Control of hot water outgoing circuit
Range: 30 to +60ºC
Accuracy: ± 0.53ºC = 3
Electrical Connection
Caution
When the temperature ranges 30 to 60ºC and 60 to 90ºC are
selected and the temperature measured by the probe is below 30ºC,
the safety feature for probe failure must be “permanent on”, until the
measured temperature reaches the minimum temperature
corresponding to the range (i.e. 30ºC for the range 30°C to 60ºC
and 60ºC for the range 60°C to 90ºC).

Main Characteristics
Multiple Applications
A single device to solve all your problems of regulation or
temperature control, from cold room to incubator.
Varying Accuracy
The accuracy can be adapted according to the application. e.g.: low
for ambient temperature regulation, high for incubator regulation.
Safety Feature for Probe Failure
To protect the installation in case of disconnection from the probe.
various connections can be made so the thermostat will be:
• Permanent OFF
• Permanent ON
• Cyclical operation: output ON 1 minute in every 4
