GENERAL SAFETY
To meet commercial hot water use needs, the high
limit safety control on this water heater is adjustable up
to 210°F. However, water temperatures over 125°F
can cause instant severe burns or death from scalds.
When supplying general purpose hot water, the recommended initial setting for the temperature control is
125°F.
Safety and energy conservation are factors to be considered when setting the water temperature on the
thermostat. The most energy-efficient operation will
result when the temperature setting is the lowest that
satisfies the needs of the application.
Water temperature over 125°F can
cause instant severe burns or death
from scalds.
Children, disabled, and elderly are
at highest risk of being scalded.
Water temperature over 125°F can cause instant
severe burns or death from scalds. Children, disabled
and elderly are at highest risk of being scalded.

GETTING STARTED
The Big Picture
This RayTemp control is designed to make recirculating domestic hot water heating systems energy
efficient. In a recirculating system, hot water is continuously pumped throughout the building. This large
loop has many branches which extend to fixtures in
the rooms. It is essentially a giant radiator which has
tremendous heat loss. By lowering the temperature of
this loop it is possible to dramatically reduce this heat
loss. The trick is knowing when to lower the temperature without running out of hot water.
Fig. 2: Hot Water Use Throughout the Day
What Comes with the Control
Before beginning the installation, it’s important to first
inspect the system and determine what materials you
will need. Some parts are included with the control
while the others you will need to provide. Check the
following list to verify that you received the following
parts.
With RayTemp, water temperatures are automatically
scheduled in anticipation of demand. So for the peak
demand in the morning, the water is preheated to a
higher temperature. The control does this automatically by recording a seven day profile of demand, and
then it uses this information to establish setpoints. The
control continually adjusts this setpoint to meet
demand, always maintaining the lowest temperature
which will fully meet user needs. This operation dramatically lessens costly heat loss, lime deposits, and
increases the life of the system.
Included in the box:

The control is preprogrammed with typical settings,
making installation very simple. However, the program
values can be adjusted to accommodate many types
of water heating systems. Output control is provided
for up to 4 stages of heat or four heaters. Two standard
temperature sensors are connected to the water heating systems at locations called “Supply”and “Return.”

INSTALLING THE
CONTROL
On the sensor end, roll the shielding and tape so it will
not contact a conductor. On the control end, the shield
should be grounded. Do not ground both ends of
the shielding.
The control should be mounted on a wall, preferably at
eye level with AC power as close as possible.
Consider the length of cable required for routing along
walls, along pipes, and for connecting the temperature
sensors.
Avoid routing wiring on or near other electrical wires,
conduit, motors, spark igniters or other sources of
high, intermittent voltage or current. EMI (spikes) can
disrupt information flow and retention.
Procedure for Installing Supply Sensor in Tank:
Notice on the bottom of the control that two of the five
knockouts have been removed for routing of cables. If
you want to use one or more of the other knockouts,
these should be removed before mounting the control
onto the wall.
1. Install sensor into dry well utilizing thermal conductive paste.
2. Install dry well into tank stat opening.
Providing 24 VAC Power to the
Control
Attaching the Temperature
Sensors
CAUTION: DO NOT connect power until all wiring
is complete and checked.
To get an accurate reading of the water temperatures,
the sensors must be in good thermal contact with the
pipe. Follow this procedure when connecting the temperature sensors.
CAUTION: DO NOT connect 120 VAC to the
RayTemp!!! Resulting damage will void your
warranty.
Procedure for Connecting Temperature Sensors to
Pipes:
1.
2.
3.
4.
5.
6.
7.
Remove any existing insulation.
Clean the pipe surface using sandpaper.
Apply thermal conducting paste to the pipe surface.
Fasten the sensor tightly to the pipe using the
black cable tie.
Attach 18 AWG shielded cable to the 6 in. leads
using wire nuts or electrical tape.
Fasten the cable to the pipe using a second black
cable tie.
Replace the existing insulation or wrap thermal
insulation tape around the pipe. Overlap each
turn and DO NOT STRETCH the tape.
The RayTemp requires an external power transformer
connected at terminals one and two. Complete and
check all wiring before connecting this transformer.
The transformer must be rated for 24 VAC at 16 VA or
higher.
When 24 VAC power is applied to the control the LCD
display will be blank for a few seconds. During this
time the RayTemp is configuring any modem that may
be connected. Afterwards, the opening screen
appears, which identifies the model number, type of
control, software version, and copyright notice.

CAUTION: Incorrect DIP switch settings may
damage the RayTemp! Make all adjustments with
ALL power off.
Four Stage Control
Fig. 6: DIP Switch Setting on Circuit Board, 2-Stage
The four relay outputs are factory set for normally
closed dry contacts. These DIP switches are located
behind the terminal block, on the right side. The black
dots in the diagram indicate where to set the 20
switches for normally closed dry contacts. As shown,
all four outputs will be the same. Relay #1 is set on
SW1 positions 6 thru 10. Relay #2 is set on SW1 positions 1 thru 5. Relay #3 is set on SW2 positions 6 thru
10. Relay #4 is set on SW2 positions 1 thru 5.
The RayTemp can control up to 2 stages:
• Two single-stage heaters
• One two-stage heater
NOTE: For On/Off and staged connections, consult
the water heater manual(s).
Connecting the Optional
“ELSA” Brand Modem
These switches are factory set and should not need
adjustment.
Raypak recommends the ELSA Microlink 56k modem
for data communication. This modem will work with
RayTemp and technical support will be provided if this
modem is installed with the correct cables. Raypak will
not be able to provide support if you use other modem
brands or build your own cables. In either case, we
strongly
recommend
that
you
test
the
RayTemp/modem connection in your office before
installing the system.
Fig. 5: DIP Switch Setting on Circuit Board, 4-Stage
The RayTemp can control up to 4 stages:
If possible, plan ahead, and have the phone line/jack
installed about two feet from the heater. Secure the
ELSA modem and connect the phone cable (that
comes with the modem) from the wall jack to the ELSA
modem jack labeled “Line”.
• Four single-stage heaters
• Two two-stage heaters
• One four-stage heater
Two Stage Control
Connect the RayTemp cable 5-423 from the modem’s
8-pin connector to the RayTemp’s “Serial to RJ11”
adapter then connect the six-line data cable from the
adapter to the RayTemp’s six-pin “RJ11” port (see Fig.
7 on the next page). Plug in the modem’s power transformer and turn on the power switch. Testing is
covered in the next section.
The two relay outputs are factory set for normally
closed dry contacts. These DIP switches are located
behind the terminal block, on the right side. The black
dots in the diagram indicate where to set the 10
switches for normally closed dry contacts. As shown,
both outputs will be the same. Relay #1 is set on SW1
positions 1 thru 5. Relay #2 is set on SW2 positions 1
thru 5.
CAUTION: DO NOT connect a live phone line
directly to the RayTemp control. Doing so will
damage the internal communication circuit!

CONNECTING A
COMPUTER
Fig. 8: Sensors Screen
Using the down-“WINDOW” key select the “SENSORS” screen and verify that each temperature
sensor is measuring the correct value. It’s best to use
a reliable temperature reading device, like a surface
thermocouple or a digital infrared thermometer.
Thermostats and mercury thermometers are frequently inaccurate. If the readings disagree by more than
two degrees there may be a problem with how the sensor is attached. Also check for correct wiring at the
terminal block.
This section explains how to connect your personal
computer to the RayTemp. Once connected, you can
view all of the front panel screens covered in the previous section. You can also retrieve the recorded data
and view color graphs of temperature and demand
profiles. "PTT" is the optional software tool for your
personal computers that works with RayTemp controls. It simulates the front panel and retrieves logged
data.

Also, buy a modem cable from Pro-Temp Controls
(800-669-8367) — at least for your first installation.
This will prevent 80% of your possible problems.
Reading Logged Data
Under the "History Report" menu item, logged data
can be retrieved from a RayTemp control, saved to a
disk file, viewed graphically on screen, or output to a
printer. To retrieve history, connect the RayTemp serial cable between the RayTemp and your laptop PC.
Then select "Retrieve". The RayTemp will transmit
logged data to your PC. This takes about one minute
at 9600 Baud. A status window will be present while
the data is being received.
To “get on-line” with the RayTemp, start the PTT software and select “Options” from the menu bar at the top
of the screen. Enter the port number (usually 1 or 2) for
the modem connected to your PC and make sure the
speed is set to 9,600. Then press Ctrl-Enter and select
“TechTerm” from the menu bar. A set of seven windows
will appear.
Start entering the phone set up commands:
The logged data consists of a report, seven detailed
daily graphs (Monday thru Sunday), and twelve
monthly graphs (January thru December). A menu will
appear from which you can view any of these graphs.
This data will be automatically saved to a disk file,
based on the file name in the report data. PTT creates
a unique name for each file by setting the last position
of the file name prefix.
“ATE1” “ENTER” Return should show “OK”. If not, reenter.
“AT&F” “ENTER” Return should show “OK”.
“AT&D0” (zero) “ENTER” Return should show “ok”.
For example, to place a call, dial “ATDT5551212” and
wait for a “Connect” message (replace the “5551212”
with your actual phone number). If the screen is blank,
type “ATE1” and try again.
The codes are 0 thru 9 and then A thru Z. For example, REDLION.GIX will be saved as REDLION0.GIX,
REDLION1.GIX, REDLION2.GIX, etc.
To view an existing history file select "Display", and
select a file by pressing enter. After the graphs are prepared, a window will appear from which you can select
any daily graph or monthly graph to view on the
screen.
NOTE: The “Modem” section on the menu bar does
not work with the RayTemp. Once you see the
“Connect” message in the TechTerm window, press
F1 and then F6 to begin communication.

Time Schedule
C6 - SELECT - Maximum Extra Temperature: C6
and C7 are an extra set of temperatures which can be
scheduled for any purpose. They will become the maximum and minimum supply temperature if the Extra
schedule is activated by the time clock. Default Temp
140°F.
TS - TIME SCHEDULE: This is a seven-day time
clock. Each line is a program for starting a new period
(such as Night) on a day (such as M-F) and at a time
(such as 6:00 am). Up to 20 lines can be displayed or
programmed using the SPACE, F4 and F5 keys.
Periods end automatically when a new one starts. The
day codes are M-F (Monday thru Friday), S-S
(Saturday and Sunday), F-S (Friday thru Sunday), and
--- (no days). The recommended setting for initial programming is --- (no days) on all settings. Changes can
be made to accommodate individual schedules.
C7 - SELECT - Minimum Extra Temperature: See
C6 above. Default Temp 130°F.
HL - SELECT - Supply High Limit: If the recovery
temperature or the return temperature is very low, the
RayTemp may need to take the supply temperature
above the programmed maximum. Regardless of any
conditions, the RayTemp will not take the supply or
any branch temperature above this high limit value. If
the supply temperature exceeds this value by 10°F
then alarm dialout will be activated. Default Temp
140°F.
Supply Temperature
The RayTemp control strategy closely matches water
temperature to demand as hot water use varies
throughout the day. The setpoint is adjusted based on
a demand profile which is recorded for the last seven
days. The RayTemp scans this profile and adjusts the
setpoint in anticipation of demand. This strategy is
complemented with a seven-day time clock which can
provide fixed temperatures during certain hours for
special requirements, such as laundry.
LL - SELECT - Supply Low Limit: The RayTemp will
not schedule the supply temperature lower than this
value (or programmed minimum). If the supply temperature drops 10°F below this value then alarm dial-out
will be activated. Default Temp 120°F.
DW - SELECT - Demand Windows in Minutes: This
value sets the time period of demand history to be
used in calculating desired temperature. The default
value should yield a smooth profile. Decreasing this
value will cause faster response to changing demand
at the risk of instability. Increasing this value will produce a very smooth desired temperature profile,
however the temperature may not rise quickly enough
during peak demand periods. The range is from 10 to
90 minutes. Default Value 40.
C0 - SELECT - Maximum Regular Temperature:
During Regular periods the desired temperature will be
set between (screen) C0 and C1 according to
demand. The time clock schedule determines when
Regular takes effect. Default Temp 140°F.
C1 - SELECT - Minimum Regular Temperature: The
supply temperature will not be set below this value
during Regular periods. Default Temp 130°F.
C2 - SELECT - Maximum Peak Temperature: C2
and C3 become the new maximum and minimum temperatures when the time clock schedule is in Peak
mode. Default Temp 140°F.
DM - SELECT - Demand % for Maximum
Temperature: This feature provides a means of
increasing temperature in oversized systems which
show very little demand. Example: Set to 50%. When
demands of 50% or more are encountered, the
desired temperature will be at programmed maximum.
Below 50% the desired temperature will be proportional between maximum and minimum programmed
values. The range is from 10 to 100 percent. Default
Value 100.
C3 - SELECT - Minimum Peak Temperature: During
peak periods the supply temperature will not be set
below this value. Default Temp 130°F.
C4 - SELECT - Maximum Laundry Temperature: C4
and C5 will be the maximum and minimum temperatures in effect if Laundry is activated by the seven-day
time clock. For laundry needs C4 and C5 will usually
be set to the same value. Default Temp 140°F.
C5 - SELECT - Minimum Laundry Temperature:
See C4 above. Default Temp 140°F.
17
DA - SELECT - Demand % for ASL Strategy: This
feature automatically adapts to manual changes in the
optional, secondary aquastat setting which may occur
after installation. This ensures continued savings even
if the aquastat is lowered. (ASL is an acronym for
Aquastat Set too Low). The strategy works by lowering
the setpoint temperature until the RayTemp has
regained control. For each 24-hour period that
demand exceeds this DA percent, the setpoint is low-
SQ - SELECT - Firing Options: Four options for
stage sequencing are available. Select number 1, 2, or
3 as follows:
ered by 5°F. Then for each 24-hour period that heater
demand is less than one half of DA, the setpoint is
increased by 1°F until the original value is restored.
The default value is 70%. The PERFORMANCE DATA
screen titled Temp Reduced by ASL Strategy will show
a value other than zero if this strategy is in effect.
Default Value 70.
#1 No Lead/Lag: Stage 1 of heater #1 always fires
first. The remaining stages and heaters will fire in
order as demand increases.
Return Temperature
#2 24-Hour Rotation: At midnight each day, the firing
order is rotated to the next heater. This distributes
the work load equally among all heaters.
The return sensor is used to compensate for seasonal
changes in loop heat loss. The strategy may raise the
supply/branch temperature in cold weather to ensure
that the last rooms on the loop have hot enough water
even during low demand periods.
#3 Lead/Lag & Rotate: With this option, heater #1
always fires first, then the remaining heaters fire in
rotation. Since some flue designs require heater
#1 to fire first; this option meets this requirement
while still providing limited rotation.
R0 - SELECT - Return Sensor Installed: Select YES
if this sensor is connected, otherwise select NO.
Default is YES.
US - SELECT - Use 24volt on/off sensing. Do not use.
DD - SELECT - Differential: Increasing DD lengthens
the heater burn cycle; decreasing DD improves temperature stability. For instance: desired=140,
deadband=1, heater turns off at 141 and on at 139.
This deadband applies equally to all stages.
R1 - SELECT - Minimum Return Temperature: If the
return temperature drops below this value then the
return sensor strategy will be activated. Above this
value, the strategy will have no effect on desired temperature. Default Temp 108°F.
D1 - SELECT - Temperature Delay Between Stages
(In addition to differential setting): This value causes successive output stages to come on according to
the deviation to target temperature. D1 activates additional heaters or stages as demand increases. For
example with a setpoint of 140°F and a temperature
delay of 1°F, stage 1 will fire at 140, stage 2 at 138,
stage 3 at 136, etc., assuming 2°F deadband.
R2 - SELECT - Return Sensor Response: This is a
multiplier which increases the desired temperature as
the return temperature drops. Example: desired = 130,
return = 100, R1 (above) = 102, R2 = 5. The desired
temperature will be increased to 140 = 130 + (102100) X 5. Default Value is 1.
Branch Temperature - Not
Used
RL - TEXT - Relay Logic (1-12): The default value is
++++++++++++.
B0 - SELECT - # of Branch Sensors Installed: Not
used.
NOTE: If you select minus (-) and the RayTemp
loses power or fails, then the heater or pump will
remain off!!! Edit text with SPACE, BACKSP, F4, and
F5 to return to a plus setting.
Relay Sequencing
(4-Stage Control)
Relay Sequencing
(2-Stage Control)
HS - SELECT - # of Heaters: Enter 1 thru 4 for the
number of heaters connected to relay outputs 1 thru 4.
This allows the RayTemp to correctly sequence
heaters and record demand.
HS - SELECT - # of Heaters: Enter 1 or 2 for the number of heaters connected to relay outputs 1 and 2. This
allows the RayTemp to correctly sequence heaters
and record demand.
SP - SELECT - Stages Per Heater: Enter the number
of stages in each heater, from 1 to 4.
SP - SELECT - Stages Per Heater: Enter the number
of stages in each heater, 1 or 2.

SQ - SELECT - Firing Options: Four options for
stage sequencing are available. Select number 1, 2,
or 3 as follows:
ues will be frozen at the values you select. To restore
the actual sensor values, press SPACE or BKSP until
Inactive ###.# appears. The RayTemp will automatically restore actual sensor values 30 minutes after
exiting this screen.
#1 No Lead/Lag: Stage 1 of heater #1 always fires
first. The remaining stages and heaters will fire in
order as demand increases.
Savings Test Setup
#2 24-Hour Rotation: At midnight each day, the firing
order is rotated to the next heater. This distributes
the work load equally among all heaters.
S1 - SELECT - Day of Month for Savings Test:
Selecting a value other than 0 (default) activates the
flip-flop savings test. This test will cause a simulation
of conditions before the RayTemp was installed - for
24 hours on the day specified every month.
#3 Lead/Lag & Rotate: With this option, heater #1
always fires first, then the remaining heaters fire in
rotation. Since some flue designs require heater
#1 to fire first; this option meets this requirement
while still providing limited rotation.
The test will run only on the day of month selected
AND on multiples of that day. Examples: Values 16
thru 28 will run test for that day only. Value 14 will run
test on day 14 and 28. Value 5 will run test on day 5,
10, 15, 20, 25, and 30. One day of testing may not
yield accurate results, while four or more days of testing will significantly cut into savings. The
recommended value is 14 (2 test days).
US - SELECT - Use 24volt on/off sensing. Do not use.
DD - SELECT - Differential: Increasing DD lengthens
the heater burn cycle; decreasing DD improves temperature stability. For instance: desired=140,
deadband=1, heater turns off at 141 and on at 139.
This deadband applies equally to all stages.
S2 - SELECT - Old (Maximum) Supply
Temperature: Enter the supply temperature prior to
installing the RayTemp if you wish to use the Acclimate
feature or Savings Test feature (above). If the preexisting control operated at a fixed temperature enter that
value here and also in the next screen.
D1 - SELECT - Temperature Delay Between Stages
(In addition to differential setting): This value causes successive output stages to come on according to
the deviation to target temperature. D1 activates additional heaters or stages as demand increases. For
example with a setpoint of 140°F and a temperature
delay of 1°F, stage 1 will fire at 140, stage 2 at 138,
etc., assuming 2°F deadband.
Savings Test Results
PD - PERFORMANCE DATA: From this screen press
F4 or F5 to view savings analysis statistics as
described below:
RL - TEXT - Relay Logic (1-12): The default value is
++++++++++++.
Average Energy Savings % displays the average
energy savings in percent during the last 365
days. This can be used to determine actual dollars
savings and payback period. This feature will not
operate unless a day of month for savings test is
selected. A flip-flop test then is activated which
alternates between RayTemp mode and baseline
mode (which has higher energy consumption).
NOTE: If you select minus (-) and the RayTemp
loses power or fails, then the heater or pump will
remain off!!! Edit text with SPACE, BACKSP, F4, and
F5 to return to a plus setting.
Sensor Override Test
ST - SENSOR TEST: This feature allows you to simulate any sensor temperature and observe the affect on
desired temperature and relay sequencing. Press
SPACE or BKSP to select a sensor, then override the
actual sensor temperature by pressing F4 or F5. Each
key stroke changes the temperature by one degree F.
Press Shift+F4 or Shift+F5 to adjust the temperature
by one-tenth of a degree (works with PTT). You can
change any or all sensors values and then look at
other screens. While in this mode all temperature val-
Baseline Heater Run Time % displays average
heater demand during Baseline mode for the last
365 days (simulating a fixed setpoint control). This
is diagnostic information used in calculating savings.
RayTemp Heater Run Time % displays average
heater demand for all heating days except baseline days during the last 365 days. This is
diagnostic information used in calculating savings.

Data Modem Setup
ASL strategy temp reduced a value other than zero
indicates that the RayTemp has reduced its setpoint
temperature by this amount. This was done to regain
control because the existing aquastat setting was lowered.
BA - SELECT - Communication Baud Rate: For
direct connect, use 9600 Baud. For modem use, set at
required 9600. Speed is activated only during poweron reset or from ER ERASE/RESET screen.

string to configure your modem. Use the Hayes-compatible modem manual for information about the AT
commands. This text will also appear on installation
reports. Edit text with SPACE, BACKSP, F4, and F5.
Once set, write down at command string.
The following screens allow you to introduce a fixed
positive or negative offset to any temperature input.
You will not normally need to make any adjustments
here since RayTemp sensors and electronics are very
accurate.
The default values in these screens compensate for a
small self-heating affect on the thermistor sensor. For
small-mass base thermistors, the offset is -2.5°F. For
thermistors mounted in housings or attached to a pipe
with thermal paste the offset is -1.5°F.
SH - TEXT - Modem Disconnect: Accepts entry of AT
commands into RayTemp memory. If a modem is
installed the RayTemp will transmit this command to
the modem to terminate the phone connection and
prevent the modem from answering another call.
