1.2 SAFETY PRECAUTIONS
• Check the supply voltage is correct before connecting the
instrument.
• Do not expose to water or moisture; use the controller only within
the operating limits avoiding sudden temperature changes with high
atmospheric humidity to prevent formation of condensation.
• Warning: disconnect all electrical connections before any kind of
maintenance.
• The instrument must not be opened.
• In case of failure or faulty operation contact your WoodMaster
dealer with a detailed description of the fault.
• Ensure that the wires for probes, loads and the power supply are
separated and far enough from each other, without crossing or
intertwining.
2. GENERAL DESCRIPTION
The ETC is designed to control the furnace temperatures between the
parameters that are selected by the operator.
3. CONTROLLING LOADS
3.1 THE REGULATION OUTPUT
The regulation is performed according to the temperature measured by the
probe.
When the appropriate temperature, SP or HY, is reached the ETC will
respond and control the combustion solenoid(s) and fan(s) accordingly.
The Hy value is automatically set under the Set Point. If the temperature
decreases and reaches set point minus differential the regulation output is
activated and then turned off when the temperature reaches the set point
value again.
