1. INTRODUCTION
The purpose of this manual is to provide a guide for technical service of Meister Cook’s 2x2 Dry Moist
Warmer for Tim Hortons (model DMW-22-TDL). This manual will provide an overview of the
operation of the DMW-22-TDL, as well as a guide for troubleshooting fault symptoms.
Before getting started, it will be helpful to have the following tools and equipment:
Phillips screwdrivers - #00, #1, #2
Right-angle Phillips screwdriver - #2
Wrench and socket set
Needle nose pliers
Side-cut pliers or scissors
Plastic Cable Ties
Multimeter
Power monitor for 120VAC circuits (e.g. Kill-a-Watt, clamp-on current meter)
Heat gun
Degreasing cleaner (e.g. Goof-Off) and stainless steel cleaner
Cleaning rags –non-abrasive, lint-free
2. BASIC THEORY OF OPERATION
The DMW-22-TDL is designed to hold potentially-hazardous hot food products at safe temperatures
for an extended period of time, without degrading the quality of the food products.
The DMW-22-TDL has (2) independently-controlled heated holding chambers, each which can hold
(2) 1/3-size food pans. Underneath each chamber is a large, finned heater. Convection, provided by
a tangential blower, moves air across the heater and transfers that heat over top the food product in
the pans; the air recirculates, and continues to heat up. Also, heat from the heater is transferred to
the pan shelf, creating a hot plate.
Above each pan is a reversible moist/dry insert. In the “Dry” orientation, heated air passes directly
over the food product; this is recommended for food products that need to maintain a level of
crispiness. The dry orientation has a “third hand” feature that holds the pan in place when it is
partially removed. In the “Moist” orientation, heated air passes over the insert, effectively creating a
top hot plate; this is recommended for food products that need to maintain a level of moisture.
The DMW-22-TDL contains 40 factory default product presets, each of which can be modified and
saved by the operator. Each preset has a distinct 4-letter name, temperature setpoint (165F –250F),
“Cook” alert time (up to 9hrs 59min) and a “Dump” product alert time (up to 9hrs 59min). See the
table below for factory defaults.

The UI has a menu of (4) product presets, (1) for each pan. These may be changed at any time. Each
row has (2) presets each. Based on which preset is selected, the highest temperature setpoint of the
two presets will determine that row’s temperature setpoint; this is why it is advised to either
program the same presets in the same row, or to program two different presets with equal
temperatures.
Also, the presets determine the countdown timers. If, in any of the 4 bins, the same preset is
selected, all timers will be based on a first-in, first-out basis; the first timer started for a given product
will flash the brightest.
There are (2) pages of menus presets, one for AM products and the other for PM products. See the
table below for factory defaults (note that v1.46 and later systems have both English and French
default menus):

Temperature feedback is provided by a thermocouple that is placed inside each intake funnel. As
part of a temperature-control circuit with the UI Board and TC Board, the temperature is measured
and compared against a programmed setpoint. As long as the measured temperature is below the
setpoint, the UI Board will signal the Power Supply to power the heater (via Triacs) at approximately
400W. As the measured temperature approaches the setpoint, the power draw on the heater is
gradually reduced. Once the measured temperature reaches the setpoint, the control circuit will
adjust the power to the heater to maintain a constant temperature; the average power draw beyond
this point is reduced. The warm-up process will take between 25-35 minutes, depending on the
setpoint.
3. OPERATING INSTRUCTIONS

Startup
Before turning on the DMW, allow it to warm up to room temperature before starting.
Make sure all dry/moist inserts are installed properly. Each chamber must have the inserts
installed in the same orientation.
Make sure the chamber front covers are installed.
Make sure food pans are installed. This provides for optimal efficiency and performance.
Plug the DMW into a 120V, 60Hz, 20 amp circuit, fitted with a properly grounded NEMA 5-15
outlet. A couple of precautions:
Make sure that 7.5A are available per DMW on the circuit. Overloading the circuit
can lead to a tripped circuit breaker, or even potentially a fire.
Do not use an extension cord. Extension cords are typically intended only for
temporary use, and commonly do not have enough current capacity for high power
draws. This can result in a fire.
Do not modify the plug in any manner. The DMW is outfitted with a NEMA 5-15 plug,
which provides for proper grounding of the system. Altering the plug may result in an

5. DIAGNOSTIC METHODS
As part of troubleshooting, there are several methods that can be used to diagnose reported failures.
The DMW-22-TDL has a set of on-board fault codes that indicate potential fault conditions:
FLT! 1111 –missing zero crossings detected

DMW-22-TDL SERVICE MANUAL
Confidential and proprietary information of Meister Cook, LLC. Not to be reproduced or used in any manner other than
with the express written permission of Meister Cook, LLC.
10 | P a g e
Under normal operation of the heater control circuit, AC line voltage crosses 0 Volts at a
frequency of 60Hz.
The power supply contains a circuit that monitors zero crossings.
If 16 half-cycles are not detected, the system will flag this condition and generate the error
code.
This fault is generally caused by a faulty power supply.
NOTE: this error code will ALWAYS occur at power down, as the heater control circuit ceases
to function. This is not an error and can be expected as normal.
FLT! 2222 –startup warming failure detected
Under normal preheating of the system, the measured temperature at the thermocouple
should rise a minimum of 16F over a 5 minute period.
This timer expires after the temperature reaches 120F.
This fault code is generated if the temperature measurement system does not detect a
minimum temperature rise of 8F over a 5 minute period.
NOTE: with Firmware v1.49, this timer has been extended to a 16F temperature rise over a
10 minute period.
This fault code is intended to indicate a failed heater, as well as prevent the heater from
overheating in the event of a fault in the movement of air and/or temperature control circuit.
However, certain installation conditions could potentially trigger a false flag:
Abnormally cold unit
Pans not installed during preheat
Effects of cool air from HVAC system
Effects of heat from another piece of equipment installed too close to the DMW
A false flag can be determined by performing the following steps:
Turn off the system and turn it back on after 10 seconds.
If the temperature is below 120F, the internal timer will reset. Monitor the system
temperatures to ensure that the appropriate temperature rise is achieved.
After clearing the fault detection parameters, ensure that the system reaches the
appropriate setpoint temperatures and is able to maintain temperature.
If a false flag continues to occur on systems running on Firmware v1.46, it is recommended to
replace the UI Board with one that is running on Firmware v1.49.
FLT! 3333 –over-temperature detected
The system has a maximum temperature setpoint of 250F.
To prevent system damage, this fault code is triggered if a temperature equal to or greater
than 285F is reached.
A false high temperature will also be reached if there is an open thermocouple circuit.
This is a preventive scheme to not allow the system to heat if a thermocouple circuit is
broken.

11 | P a g e
In addition to the fault codes, current measurement devices can also be helpful. A power meter, such
as a “Kill-a-Watt”, can measure power draw. Each heater should draw 400W during preheat, and the
power draw should gradually be reduced as the setpoint is approached. A typical power draw of
approximately 800W at startup is typical. Power draws significantly lower may indicate an open
heater circuit. Power draws significantly higher may indicate a short circuit or a faulty power supply.
When trying to isolate a faulty heater or power supply, it may be helpful to test power draw with
each heater connected one at a time.
Finally, a heat gun can also be helpful in determining if the temperature measurement circuit is
working properly. By simply directing a stream of hot air of a known temperature at the
thermocouple, a corresponding rise in temperature should occur at the UI.
6. TROUBLESHOOTING
Refer to the matrix below for a step-by-step approach to navigating through various reported
symptoms. Please note that it is possible not all failure symptoms have been documented. As
symptoms appear, this guide will be updated. Also note, if the recommended steps do not resolve

Reported fault symptom(s)
Frequency of fault symptom(s)
Make sure the caller is in front of the system under complaint. It is essential for them to be able to
exactly describe the failure symptom(s). When in doubt, err on the side of asking too many
questions.
If the caller is reporting problems with temperature and/or quality of food products being served
from the DMW, it is essential to re-direct them to the system to determine if there is an actual fault
with the DMW. Food product temperature and/or quality can potentially be linked to several factors
unrelated to the DMW.
