Installation

Conﬁ guring the High Limit Sensor

Dip Switch pin 3 is used to set the high limit sensor op-

eration to one of two possible operational modes:

• OFF sets the high limit sensor as a slab regulating tem-

perature sensor.

• ON sets the high limit sensor as an ambient air sensor.

OFF is the factory default.

Index 8 shows how to conﬁ gure the high limit sensor mode at

the DIP switch.

Factory Use Only

DIP switch pin 4 is for factory use only. The use of pin 4

except by authorized personnel may lead to improper operation

of the SCP-120

Bypassing the High Limit Temperature Sensor

If, for any reason, you need to operate the system with-

out the High Limit Temperature Sensor (for trouble shooting or

while waiting for a replacement sensor) you can temporarily re-

place the sensor with a 470K resistor. The resistor will allow the

system to run as if the sensed temperature was 40°F (4.4°C).

Refer to Figure 23 for placement of resistor.
