ICM Controls MP2010L Installation, Operation & Application Manual page 2

Installing and Changing Batteries
For Battery Thermostat Operation
If your LCD is blank, or displaying LO BAT, the batteries are not installed or
need to be changed. We suggest you change the batteries at least once a year,
or whenever the LO BAT warning displays.
Remove the cover, and install the two "AAA" alkaline batteries into the battery
compartment. Proper battery installation is important! Make sure the positive
ends of the batteries match the positive terminals in the battery compartment.
For Hardwired Thermostat Operation
Batteries are not required when a common wire is connected to the C terminal of the MP2010L
thermostat.

temperature.
Press the up or down button to set differential value.
Press the RIGHT switch to advance to the next screen.
3. Heat Pump and Non-Heat Pump – Set to heat pump, or non-heat pump
system. For heat pumps, there will be a compressor time delay for heating
and cooling.

Operating Modes
OFF Mode
• In this mode, the thermostat will not turn on the heating or cooling devices (manual fan can operate)
• OFF mode is also used to access the configuration screens
Cool Mode
• In this mode, the thermostat controls the cooling system
Heat Mode
• In this mode, the thermostat controls the heating system
ARC Detection Technology
This thermostat comes enabled with ICM Controls' patent-pending Abnormal Rate of Change
(ARC) detection technology that helps deter tenants from attempting to "trick" the thermostat into a
false reading. Upon sensing an abnormal rise or drop in temperature, the thermostat operation will
automatically default into a lockout sequence. The display will show Err for an abnormal RISE in
temperature, or Erd for an abnormal DROP in temperature. When the thermostat returns to normal
operation, the error message can be cleared with the press of any button.
Troubleshooting
Symptom
No display Check for 24 VAC at thermostat; display is blank when 24 VAC
is not present or if batteries are completely discharged
System fan does not come on Verify wiring is correct, check Gas/Electric jumper position (see
properly Parts Diagram)
All thermostat buttons are Verify 24 VAC is present; unit locks out when 24 VAC is not
inoperative present with no batteries installed
No response with first button First button press activates backlight only when back light is
press configured "ON" (see Configuration Mode Setting 9)
Heat or Cool not working RC/RH jumper must be installed on single transformer systems
For heat pumps, Non-HP jumper must be on HP pins
Thermostat turns on and off too Adjust temperature differential
frequently (see Configuration Mode Setting 2)
Fan runs continuously Slide FAN switch to auto to turn fan off
#4 to #8 configuration screens Thermostat has the permanent lockout function activated
not available (see Lockout Feature and Configuration Mode Setting 8)
Heat or Cool not coming on Verify wiring is correct, verify RC/RH jumper is in place (for
single transformer system)
Err or Erd on display Abnormal Rate of Change (ARC) detected. Thermostat defaults
into lockout sequence. When normal operation resumes, error
message can be cleared with press of any button
on display Replace batteries with two fresh "AAA" alkaline batteries
Problem not listed above Press Reset button once*
