K. Basic Troubleshooting Techniques

Being familiar with the sequence of operation on Standard Controlled Operating Units or the operation of the Remote Thermostat Controlled Units is important. The following questions and answers may help to identify performance problems.

Environmental Effects - Cooling Mode

Is unit sized to room size area and heat load demand?

The number of people in the room, number of electrical devices, solar gains, etc. are all variable items that can affect proper sizing of the unit. Friedrich recommends that you consult with an applications engineer for proper sizing.

Environmental Effects - Heating Mode

Is unit properly sized to room area and heat load demand?

Is the outdoor temperature 60°F or below?

The unit is designed for outdoor temperatures above 60°F.

Is the indoor temperature 80°F or above?

Ambient indoor temperatures of 80°F or above will take a longer period of run time to cool down the area. Long run times may indicate that the unit is undersized.

Is indoor humidity high?

This condition will cause the unit to operate longer to remove humidity before noticing any cooling effect.

Is the outdoor temperature 70°F or above?

The unit is designed for outdoor temperatures below 70°F.

Is the indoor temperature 60°F or below? Ambient indoor temperatures of 60°F or below will take a longer period of run time to heat the area. Long run times may indicate that the unit is undersized.

Has the room area been increased where the unit is located?

If the area where the unit is located has been increased, the unit may not provide adequate heat.

Has the heat load been increased by additional devices such as computer equipment, or has the room area been increased where the unit is located?

If conditions have changed, the unit may not be able to cool and condition as effectively as previously planned.
