• The SQ-Elite-8S will turn all boiler relays off when it is in Summer setting. The
Message Display Line will read Summer to show status.
• When in Winter, the SQ-Elite-8S will activate the System relay whenever the Outdoor
temperature falls to or below the Outdoor Cutoff setting. In addition, it will begin
heating whenever the System pressure falls below the Set Point. The Message Display
Line will not display any season information.

Summer to turn off all heating instead of turning off the control. This will preserve the
battery life.
