STEP EIGHT TROUBLESHOOTING
As in any troubleshooting procedure, it is important to isolate a problem as much as possible before proceeding. The Error Messages
and
Test button greatly simplify troubleshooting of the 201. When the control is displaying an Error Message, identify the fault from the
look-up table on page 20 and follow standard testing procedures to confirm the problem. If you suspect a wiring fault, return to steps
three, four and five, and carefully check all external wiring and wiring connections.
Sensor and Internal Faults
Whenever a fault is detected in any of the sensors, an error message will be displayed in the LCD.
Outdoor Sensor Fault
When the outdoor sensor is open circuited or missing, the control will display
OUTDOOR OPEN. If a short circuit occurs, the control
displays OUTDOOR SHRT. When a fault with the outdoor sensor is present, the control assumes a fixed outdoor temperature of 32
°
F.
During snow melting operation, the control assumes an outdoor temperature of 20
°
F.
Boiler Return Sensor Fault
When the Boiler Return Sensor is open circuited or missing and the Boil RET adjustment is not set to OFF), the control will display Boil
RET OPEN. If a short circuit occurs, the control displays Boil RET SHRT. When a fault with the boiler return sensor is present, the
control continues to operate as if no return sensor is installed. If the system is providing snow melting, the mixing 2 section is turned off.
Supply 1 Sensor Fault
When the Supply Sensor of the mixing 1 section is open circuited or missing and MODE 1 is not set to OFF, the control will display
SUPPLY 1 OPEN. If a short circuit occurs, the control displays SUPPLY 1 SHRT. When a fault with the Supply Sensor is present,
the control shuts down the mixing 1 section.
Supply 2 Sensor Fault
Operates in a similar manner as the mixing 1 section.
IND / Zo 1
If
ZOIN or INDR is selected and an open circuit is seen on the Zo 1/Ind terminal, the control will display IND/Zo 1 OPEN. If a short
circuit occurs, the control displays IND/Zo 1 SHRT. When a fault is present and ZOIN is selected, the control ignores any demands
from the zone control. If INDR is selected, the control provides outdoor reset but no indoor temperature feedback.
IND / Zo 2
Operates in a similar manner as the mixing 1 section.
