Operation
Power OFF
(See wiring diagrams below for wiring connections.)
Configurations
With no power applied to the red-white wire, all lights are off. Power can
be wired directly from appliance 120 VAC terminal to maintain power at all
times. Or jumper red-white wire and black-green wire to cycle power with
the appliance limit circuit.
s Control kits — 90000 controls mount to a standard 4x4 J-box,
supplied with the control. Mount the box directly to a well (new or
existing) with hardware supplied, or panel mount. See below for
dimensions.
s Well kits — Wells for 90000 sensors are available in the sizes shown
below. Well kits include sensor mounting hardware designed to hold
sensor securely in position.
s Sensors — Sensors are available in single and dual configurations.
s Notice: UL-Listed control — UL-Listed controls are supplied complete with control, J-Box, well, sensor, and mounting hardware.
Power ON
When power is applied to the red-white wire, the green LED turns on.
Self-test
When power is applied, the 90000 performs a self-test, checking sensor(s)
and microprocessor and verifying limit contacts are open. The power-up test
lasts from 3 to 5 seconds. The 90000 continues diagnostic checing during
the operating cycle as well. Any self-check failure causes a lockout (see
below).
Operate
If the temperature at the operating sensor(s) is below setpoint by at least the
fixed differential, the control closes the operating limit contacts. The amber
LED turns on.
Stand-by
When the operating sensor(s) see setpoint temperature or above, the 90000
opens the operating limit contact. The amber LED turns off.
Limit action
90000A, B or C: If the high limit sensor(s) see a temperature above high
limit setting, the control opens the high limit contacts, turns on the red LED
and checks the operating limit contacts. If the operating limit contacts are
open, the control will automatically reset when temperature drops below
high limit setting minus differential. The high limit contacts close and the
red LED turns off. Diagnostic failures invoke “limit action” until cause is
cleared.
Lockout
If the high limit sensor(s) sees a temperature above high limit setting and
the 90000A, B, or C model finds the operating limit contacts closed, the high
limit contact opens, the red LED turns on and lockout occurs. If the high
limit sensor on the 90000CE sees a temperature above the high limit setting,
the high limit contact opens, the red LED turns on and lockout occurs. When
the temperature drops below high limit setting minus differential, reset the
control by pressing the manual reset button. The control will not reset by
cycling power off and on.
Latch-up

the operating cycle as well. Any self-check failure causes a lockout (see
below).
Operate
If the temperature at the operating sensor(s) is below setpoint by at least the
fixed differential, the control closes the operating limit contacts. The amber
LED turns on.
Stand-by
When the operating sensor(s) see setpoint temperature or above, the 90100
opens the operating limit contact. The amber LED turns off.
Limit action
If the high limit sensor(s) see a temperature above high limit setting, the
90100 opens the high limit contacts, turns on the red LED and checks the
operating limit contacts. If the operating limit contacts are open, the control
will automatically reset when temperature drops below high limit setting minus
differential. The high limit contacts close and the red LED turns off.
Lockout
If the high limit sensor(s) sees a temperature above high limit setting and
the 90100 finds the operating limit contacts closed, the red LED turns on and
lockout occurs. (Lockout also occurs on any diagnostic test failure.) When
the temperature drops below high limit setting minus differential, reset the
control by pressing the manual reset button. The control will not reset by
cycling power off and on.
Latch-up
If the 90100 locks out three consecutive times, it enters latch-up. Reset from
latch-up requires a special procedure, intended to require licensed serviceman intervention. During latch-up, the red LED stays on and the green LED
flashes. Reset as follows:
............
Temperature must be less than high limit setting minus differential.
............
Hold reset button at least 10 seconds. The green LED flashes faster.
............
Continue holding button another 20 seconds. The control resets and the red
LED turns off.

Control kits — 90224 controls mount to a standard 4x4 J-box,
supplied with the control. Mount the box directly to a well (new or
existing) with hardware supplied, or panel mount. See below for
dimensions.
Well kits — Wells for 90224 sensors are available in the sizes shown
below. Well kits include sensor mounting hardware designed to hold
sensor securely in position.
Sensors — Sensors are available in single configurations.
Indicator LED’s
90224 controls have a green LED (power/lockout indicator) and
amber LED (operation indicator).
Power OFF With no power applied to black/red wire, all lights are off.
Power ON
When power is applied to the black/red wire, the green LED turns
on, flashing every 3 seconds.
Self-test
When power is applied, the 90224 performs a self-test, checking
the sensor and microprocessor. The power-up test lasts from 3
to 5 seconds.
The 90224 continues diagnostic checking during the operating
cycle as well. Any self-check failure causes a lockout (see below).
Call for heat When the temperature at the operating sensor is below setpoint
minus fixed differential, the 90224 break-on-rise contact is closed,
or the make-on-rise contact is open. The amber LED is on.
Stand-by
When the 90224 operating sensor reaches setpoint temperature
or above, the 90224 break-on-rise contact opens; or the makeon-rise contact closes. The amber LED turns off.
Lockout
If the control detects a diagnostic failure, lockout occurs. During
lockout, the green LED flashes every second.
After the temperature drops below setpoint minus differential,
reset the control by turning power off, then back on. The green
LED will flash more slowly, every 3 seconds.
Power must flow through the contacts in the direction shown. Changing
flow direction will cause the control to lockout or fail to operate.
The 90224 is polarity-sensitive with some controls. If the 90224 goes to
lockout on power up, disconnect power. Swap the wires coming to the
black/red and black/yellow lead wires. Restore power and restart.

Electrical shock hazard: Disconnect power to appliance when wiring or
servicing any electrical component.
Operation
(See wiring diagrams below for wiring connections.)
Power OFF
With no power applied to the red-white wire, all lights are off. Power can be wired
directly from appliance 240 VAC terminal to maintain power at all times.
Power ON
When power is applied to the red-white wire, the green LED turns on.
Self-test
When power is applied, the 90320 performs a self-test, checking sensor(s) and
microprocessor and verifying limit contacts are open. The power-up test lasts from
3 to 5 seconds. The 90320 continues diagnostic checking during the operating cycle
as well. Any self-check failure causes a lockout (see below).
Operate
If the temperature at both operating sensors is below setpoint by at least the fixed
differential, the control closes the operating limit contacts. The amber LED turns
on.
Stand-by
When either operating sensor sees setpoint temperature or above, the 90320 opens
the operating limit contact. The amber LED turns off.
Limit action
If the high limit sensor sees a temperature above high limit setting, the 90320 opens
the high limit contacts, turns on the red LED and checks the operating limit contacts.
If the operating limit contacts are open, the control will automatically reset when
temperature drops below high limit setting minus differential. The high limit contacts
close and the red LED turns off.
Lockout
If the high limit sensor sees a temperature above high limit setting and the 90320
finds the operating limit contacts closed, the red LED turns on and lockout occurs.
(Lockout also occurs on any diagnostic test failure.) When the temperature drops
below high limit setting minus differential, reset the control by pressing the manual
reset button. The control will not reset by cycling power off and on.
Latch-up
If the 90320 locks out three consecutive times, it enters latch-up. Reset from latch-up
requires a special procedure, intended to require licensed serviceman intervention.
During latch-up, the red LED stays on and the green LED flashes. Reset as follows:
............
Temperature must be less than high limit setting minus differential.
............
Hold reset button at least 10 seconds. The green LED flashes faster.
............
Continue holding button another 20 seconds. The control resets and the red LED turns
off.
•
Control kits — 90320 controls mount to a standard 4x4 J-box,
supplied with the control. Mount the box directly to a well (new or
existing) with hardware supplied, or panel mount. See below for
dimensions.
Well kits — Wells for 90320 sensors are available in the sizes shown
below. Well kits include sensor mounting hardware designed to hold
sensor securely in position.
Sensors — Sensors are available in single and dual configurations.
Power must flow through the contacts in the direction shown. Changing
flow direction will cause the control to lockout or fail to operate.

Power OFF — With no power applied, the thermostat (TT) circuit and all
output contacts are de-energized. All LED’s are off.
Power ON — When power is applied to the L1/L2 terminals, the thermostat
circuit is energized. Voltage (24 VAC) is applied to the thermostat terminals.
The 90524 starts a self test to check the sensor and the microprocessor,
and to verify that the limit contacts are open. The 90524 becomes fully
operational after this 2-second self test.
or
Soft lockout — Green light flashing once per second,
burner light off, burner contact open, and circulator light on or off — occurs
if control senses internal failure or sensor problem (open or shorted sensor).
The control will revert to normal operation if the problem is corrected within
15 seconds. Otherwise, the control enters hard lockout.
Hard lockout — Green light flashing twice per second, burner light off and
burner contacts open, circulator light on and circulator contacts closed —
occurs when burner contact is sensed closed, and does not clear after two
attempts. Reset by cycling power off/on.
Latchup — Green light off, burner light off, B1 contact open, circulator light
on, and ZC and C1 contacts closed — occurs when burner contact is sensed
closed, and does not clear after three attempts. Not resettable — requires
control replacement.
Fault log
90524 controls self monitor and indicate fault conditions with the LED’s. Fault conditions
are recorded in the retrievable fault log. For applications that might encounter unexplainable
control outages, contact Carlin Technical Support for instructions to access the fault log and
interpret the results.

Instructions
Functions
F
Front
s Carlin’s 90524A can be operated as either a triple limit control or a cold-start
control, determined by the setting of the LOW LIMIT adjustment.
s Triple limit operation (LOW LIMIT on): Provides adjustable high limit setting and maintains an adjustable minimum temperature in the boiler (low
limit setting) while in stand-by (no space heating call); used for tankless
heater applications. (See Figure 3 , page 4.)
s Cold-start operation (LOW LIMIT off): Provides adjustable high limit setting and low temperature protection (delays circulator start until the boiler
is heated above the fixed minimum temperature setpoint); used to prevent
condensation in the boiler on cold start. (See Figure 4 , page 4.)
s The 90524A provides input from zone controllers or relays (ZR contact) and
output to enable circulators (C1 contact) or zone controllers (ZC contact).
The gas valve/burner output is on the B1 terminal. Call for heat input is on
the T-T terminals.

failure occurs, the LED blinks and the contact
opens. The control will reset when the failure
is removed and power is cycled.
Call for Heat
When the temperature at the sensor is below
set point minus fixed differential, the control
powers the limit relay (break-on-rise contact
closes). On the 90200GL, the High Fire
LED turns ON and the Low Fire LED turns
OFF. On the 90200AL, the Amber LED turns
ON. When temperature is at or above set
point, the contact opens. On the 90200GL,
the High Fire LED is turned OFF and the Low

intended to require licensed serviceman intervention. During
latch-up, the red LED stays on and the green LED slow flashes.
Reset as follows:
2.12”
After boiler is less than high limit setting minus differential:
. . . . . . . . . . . . Hold reset button at least 10 seconds. The green LED flashes
faster.
. . . . . . . . . . . . Continue holding button another 20 seconds. The control resets
and the red LED turns off.

High Limit Test “Hi-Test” mode (90000CEL ONLY), used to test “High Limit Reset” at operating boiler temperature. Start test with system operational and calling for heat. Turn setpoint full clockwise to HiTest position. Green LED flashes fast. The setpoint now adjusts
both the high and operating limits. Turn setpoint slowly counter
clockwise until Lockout occurs. Now the setpoint temperature
equals the hi-limit sensor temperature. Test is complete, adjust
setpoint to the desired operating limit. Remove from lockout.

Operation (See wiring diagrams for connections)
Power On
When power is applied to unit, the green LED turns ON.
Self Test
90200HL: When the fault log display is complete, the self test
checks the sensor and the microprocessor and verifies that all
systems are operational. This test lasts up to 15 seconds before the
control becomes fully operational. During the self test, the green
LED blinks at a rate of 3 seconds per blink.
Lockout
90000CEL: When the temperature at the High-Limit sensor reaches
the High-Limit set point or a diagnostic fault occurs, the control
goes into Lockout. The red LED turns ON and both contacts open.
The control will automatically reset when all diagnostic faults are
removed. Manual reset is required to resume operation after an
over temperature High-Limit Lockout.

6.75”
90000CEL: When the temperature at the Operating-Limit sensor is
below the Operating-Limit set point minus the fixed differential, the
control powers the operating relay and it’s break-on-rise contact
closes. The Amber “Call for Heat” LED turns ON.
When the temperature is above the set point, the contact opens and
the Amber LED Turns OFF.
5.25”
High-Fire Calling 90200HL: When the temperature is at or below the operating temperature minus 1/2 the band temperature, the control is requesting
High Fire and the LED is ON. When the temperature is at or above
the operating temperature plus 1/2 the band temperature, the
control is requesting Low Fire and the LED is OFF. In between, the
control modulates the motor to a position proportional to the sensor
temperature. The LED blinks with an ON time proportional to this
position.
(90000CEL)
If the 90000CEL locks out three consecutive times, it enters latchup. Reset from latch-up requires a special procedure, intended to
require licensed serviceman intervention. During latch-up, the red
LED stays on and the green LED slow flashes. Reset as follows.

High Limit Test “Hi-Test” mode (90000CEL ONLY), used to test “High Limit Reset”
at operating boiler temperature. Start test with system operational
and calling for heat. Turn setpoint full clockwise to Hi-Test position.
Green LED flashes fast. The setpoint now adjusts both the high
and operating limits. Turn setpoint slowly counter clockwise until
Lockout occurs. Now the setpoint temperature equals the hi-limit
sensor temperature. Test is complete, adjust setpoint to the desired
operating limit. Remove from lockout.

Configurations
To install a new immersion well:
Carlin EZ-Temp components are available in the following configurations, allowing use
with existing wells in addition to EZ-Temp wells.
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: Press the sensor retainer plug (11) into the well until it securely
holds the sensor wires, to prevent movement of the sensor.
