Installer/servicer — Except where specifically stated otherwise,
this manual must be used only by a qualified service technician.
Read and follow all instructions in this manual and in the appliance
manual. Failure to comply with this or other requirements in this
manual could result in severe personal injury, death or substantial
property damage.
This symbol calls out a hazard that could cause severe personal
injury, death or substantial property damage if the instructions
given are not followed.
Wiring: Refer to EZ-Temp data sheet for wiring information.
Verify ratings: Verify the ratings of the control meet the
requirements of the appliance as specified in the appliance
instructions. Refer to the EZ-Temp control data sheet for
required electrical supply and load ratings. Verify that the
controls, wiring and installation comply with all applicable
codes.
Electrical shock hazard: Disconnect power to appliance

Scald hazard: Water hotter than 130°F can cause seri-
ous burns or death. Follow water heating appliance
manufacturer’s guidelines when installing temperature
limit controls - DO NOT install a control that can be set
at a higher temperature than specified. Also verify that
the installation includes all water temperature regulating
means needed to ensure the safety of building occupants,
in compliance with all applicable codes.
Verify operation: Test the controls/appliance to verify the
appliance operates as specified in the appliance manual

EZ-Temp Microprocessor Temperature Control — Instruction manual
– 2 – MNEZTA 042016
Configurations
Carlin EZ-Temp components are available in the following configurations, allowing use
with existing wells in addition to EZ-Temp wells.
Surface-mount sensors are also available.
• Control kits
Control kits include the control only.
• Well kits
Well kits include a well (item 1), rubber sensor retainer (item 3), retainer
washer (item 4), jam nut (item 5), and lock washer (item 8).
• Sensor Kits
Sensor kits include only the sensor (item 2). Sensors are available in single
and dual configurations (two sensors in the same assembly). For controls
that use multiple sensors, obtain separate sensor kits or a sensor kit with a
dual sensor.
Install sensor(s)
To install a new immersion well:
1. Turn off power to the appliance and close isolation valves.
2. Follow appliance instructions to drain the appliance so water line is below
the insertion tapping.
3. Remove existing well and sensor. Apply a small amount of pipe dope to the
new well and secure in tapping.
4. Insert EZ-Temp sensor into well and secure sensor in place as described in
the following.
5. Refill appliance with water, following appliance manual procedures.
When routing sensor wires, avoid sharp edges and use strain
relief bushings at penetrations to prevent movement or electrical
shorting of the sensor. Sensor wires are not low voltage, and must
be routed in conduit.
Configuration A: Sensor and well only
1. Insert the sensor into well (1) until the sensor (2) tip bottoms in the well
socket.
2. EZ-Temp well: Slide the rubber retainer (3) over the sensor wires until it
firmly contacts the sensor casing. Slide the retainer washer (4) and the jam
nut (5) over the wires. Thread the jam nut into the well until snug.
3. Existing well: Use the retainer spring (11) with rubber retainer (3) to seat the
sensor in the well.
Configuration B: Sensor, EZ-Temp with Carlin well
1. Insert the sensor into well (1) until the sensor (2) tip bottoms in the well
socket.
2. Slide the rubber retainer (3) over the sensor wires until it firmly contacts the
sensor casing. Slide the retainer washer (4) over the wires.
3. Slide the lock washer (8), wiring base (7), and jam nut (5) over the wires.
4. Thread the jam nut into the well and tighten to secure the wiring base and
sensor in place.
Configuration C: Sensor, EZ-Temp and non-Carlin well
1. Install well clamp assembly into wiring base.
2. Assemble wiring base to well.
3. Insert the sensor into well (9) until the sensor (2) tip bottoms in the well
socket.
4. Slide the rubber retainer (3) over the sensor wires until it is near the well (9).
5. Assemble retainer spring (11) about retainer (3) then use retainer spring/
retainer to bottom the sensor in the well. The retainer spring will lock in the
well.
Wire the control
1. Control wiring must be routed through conduit or electrical enclosures. Follow
all applicable codes and the appliance manual.
2. Insert sensor wires into the connector(s) on the face of the circuit board.
3. Follow the burner and appliance wiring diagrams to connect the control(s)
into the appliance limit circuit.
4. For specific applications, contact your Carlin supplier for further information.
Set the control
1. Follow the appliance manual to set the correct limit temperature for the
appliance. To adjust the EZ-Temp control:
Setting – (How to enter = Hold up and down buttons for 3 seconds while in
NORMAL OPERATION)
• In SETTING MODE, the user is able to adjust the operating limit (via setting the
set temperature). Once in this mode, the display will begin flashing the current
set temperature. The display will increase one degree per UP or DOWN button
push or 10 degrees per second the button is held.
2. Test the operation of the appliance and the new limit control(s) to verify
correct operation.
3. NOTE: EZ-Temp controls have a subtractive differential – control contacts
trigger when the temperature setting is reached. Contacts reset after tem-
perature drops below setpoint minus the differential amount. aCarlin well
