reduce ‘overshoot’ when the Chiller pump
is turned off (the cold water remaining in
the jacket will continue to chill).
Connecting power
The Chiller compressor has a 120V (NEMA
5-15) plug which can be plugged either
into a wall receptacle or into the ‘chilling’
receptacle (marked by a blue snowflake)
on the left side of the BREWHA ETC
temperature controller (the front right
receptacle on the old model, white ETCs)
or the Chiller plug on the Programmable
Touchscreen Power Controllers (only the
ETC will be referenced from here, but
the same applies for the Touchscreen
Controllers).
If the Chiller is plugged into the wall,
when the power is switched on, it will
turn on immediately and begin to chill
the water bath to the temperature indicated by
the mechanical thermostat. Once it reaches the
temperature, the compressor will shut off and will
turn on again when the temperature of the water
bath rises. It will turn on and off and maintain the
temperature even if the fermenter does not need
it. If the Chiller is plugged into the ETC, the Chiller
will only turn on when the ETC senses that the
fermenter is warming up and will power the chilling
receptacle on the ETC.
Controlling temperature in the BREWHA
fermenter
The BREWHA ETC senses the temperature starting
to rise in the fermenter and allows power through
to the chilling receptacle on the ETC.
Setup A (Figure 48): If the Chiller compressor is
plugged into a wall receptacle, the Chiller pump
should be plugged into the chilling receptacle on
the ETC using a cord adapter (the pump has an
IEC 320 electronic plug and an adapter allows it to
