The Multi-MOD Platinum normal display layout uses the second row from the top for operating messages
The following is a list of the most common Message Display Line information:
Ack Received The Internet control has acquired connection to the Heat-Timer communication
server This message is displayed for 2 seconds after one minute of power up
BST: 170˚F Boost is active The new target temperature is 170°F See "Boost and Early
Shutdown" on page 34
DHW Call (180˚F) A DHW Call is active The DHW Set Point is 180˚F See "DHW Set Point" on page 29
Fast Cool Down ESD (Early Shutdown) is active The new target is equal to the Fast Cool Down
setting See "Fast Cool Down" on page 30
Holding Until 150˚F The lead stage is in Last-Stage-Hold This example shows that the lead stage will
turn off when system temperature reaches 150˚F See "Last-Stage-Hold" on page 37
Internet Control The control is an Internet control and the display is in Screen Saver Mode See
"Internet Communication" on page 45
Lag Delay: 123 The lead stage is at 100% and the remaining purge time to start the lag boiler in
seconds is 123 See "Lag Delay" on page 37
Network Panel The control has a communication package installed and the display is in Screen
Saver Mode
Prove Failure After boilers have run for a while, Prove signal was opened All boiler outputs are

"Purge Delay" on page 36
Shutdown Active The Shutdown input is shorted/active No stages will be active See "Shutdown
Wiring" on page 18
Shutdown by EMS The EMS set point signal is below 2mA or above 22mA See "EMS Input Mode" on
