Outdoor Cutoff Temperature; Minimum Water Temp; Maximum Water Temp - Raypak TempTracker mod+ Hybrid Installation And Operation Instructions Manual

32 Raypak, Inc.
• If required: Adjust the Water Offset in mild weather. If the ambient building
temperatures are too warm in mild weather, decrease the offset. If the ambient building
temperatures are too cold in mild weather, increase the Water Offset.
• The rule of thumb for baseboard radiation is to change the offset 4°F for every 1°F you wish
to change the building temperature. In radiant heat applications, change the offset 1F° or
2F° for every 1F° you wish to change the building temperature.

outdoor cutoff temperature

Adjustable: Off, from 20ºF / 70ºC - 100ºF / 38ºC, On
Button: MENU/System Target/Offset/Outdoor Cutoff
• The control will turn heating off if the outside temperature rises above the Outdoor Cutoff.
This setting shall not affect any indirect DHW requirement.
• The Outdoor Cutoff screen will automatically appear after setting the Offset.
• When the outdoor temperature falls to the adjustable Outdoor Cutoff temperature, the
TempTracker mod+ Hybrid will operate the boilers to hold the calculated temperature.
• When the outdoor temperature rises to the Outdoor Cutoff plus a 2°F differential, the
TempTracker mod+ Hybrid will turn all boilers off. The System relay will remain energized
for the Run-On delay then de-energize.
• The Outdoor Cutoff can be set from 20°F to 100°F. In addition, it can be set to ON or
OFF. In the ON position, the System Relay will run regardless of the Outdoor temperature
(OD) and the burner stages will be active to hold the calculated water temperature. (Note:
The lowest water temperature the TempTracker mod+ Hybrid will circulate is 70°F. If the
Outdoor Cutoff is turned ON and the Season is set to Winter, the TempTracker mod+ Hybrid
will circulate at least 70°F water even in the hottest of weather.) In the OFF position, the
system pump will always be off and all burner stages will be off.

Minimum Water temp

Adjustable from 50ºF/10ºC to 180ºF/82ºC
Button: MENU/System Target/Offset/Outdoor Cutoff/Minimum Water Temp
• The Minimum Water Temperature must be set to the boiler manufacturer's specification.
The TempTracker mod+ Hybrid will calculate the Set Point based on the Outdoor
temperature (OD), the Reset Ratio, and the Offset value. The TempTracker mod+ Hybrid
will control all boilers to hold either the Set Point temperature, or the Minimum Water
Temperature, whichever is higher.
• The Minimum Water Temperature must be at least 20°F lower than the Maximum
Temperature (See next setting).

Maximum Water temp

Adjustable 70ºF/21ºC - 220ºF/104ºC
Button: MENU/System Target/Offset/..../Maximum Water Temperature
• This is the highest temperature heating water the TempTracker mod+ Hybrid will circulate
through the heating system.
• When using a radiation system, it should be set according to the tubing or floor
manufacturer's specification.
• The Maximum Temperature must be at least 20°F higher than the Minimum Temperature
(See previous setting).
