Maintenance/DHW Settings/Demand Schedule
• The Peak and Light Demand Schedule activates the respective differential. Each day of the
week has 4 Peak Times and 4 Light Times that can be set differently.
• When in the DHW Schedule, pressing the NEXT button on the Platinum control displays
the next Schedule entry.
• Pressing the DAY button on the Platinum control displays the next week day entry.
• Domestic hot water Demand Schedule can be accessed on the ICMS web site by selecting
Schedules from the Platinum control Live Session then selecting the DHW Demand.

Internet Alarms Through ICMS
Sensor Fault
• If any of the sensors failed or were disconnected from the Platinum Control, the control will
energize the respective relay. Make sure that the boiler/water heater has its operating and
limit controls installed and able to control the boiler/water heater temperature during sensor
failure to avoid hazardous situations.
• To setup an alarm delivery for a sensor fault situation, select the sensor on the ICMS web
site. Select Alarm Delivery Setup and then Add Delivery for the Sensor Fault.
WARNING
The boiler/water heater must have its operating and limit controls installed and wired in
a way so that the Supply sensor fault or DHW Energy Saver communication Error will
not cause a hazardous situation. It is the responsibility of the installer to make sure of
the system operation and users safety during sensor fault or communication error.
Heat-Timer recommends the installation of a precision tempering valve, ETV, or TMC to
help protect the output from excessive temperatures.
Communication Error
• If the DHW Energy Saver lost its communication to the Platinum control for more than 1
minute, it will energize both output relays. Make sure that the boiler/water heater has its
operating and limit controls installed and able to control the boiler/water heater temperature
during Communication Errors to avoid hazardous situations.
Troubleshooting and LEDs
When the DHW Energy Saver cover is removed, several LEDs will be available for viewing. These LEDs are used for diagnosing
and troubleshooting many communication and relay operation.
• A power Red LED indicates that the unit has the proper voltage to operate.
• A Green LED blinks every second to indicate there is communication between the DHW Energy Saver and the Platinum control.
If that communication fails, this LED will keep blinking for 15 seconds then it will turn off. After an additional 45 seconds, the
control will energize both output relays.
• Each of the output relays has a Red LED that is turned on whenever that relay is energized.
