AUXILIARY HEAT RANGE
The installer must select the auxiliary heat airflow approved for
application with kw size heater installed. If no heater is installed,
skip this step. Each select pin is marked with a range of heaters for
which airflow (also marked) is approved. For increased comfort
select the narrowest kw range matching the heater size, for
example, 0-10 for a 10-kw heater. This airflow must be greater
than the minimum CFM for electric heater application with the
size system installed for safe and continuous operation. Note that
airflow marked is the airflow which will be supplied in emergency
heat mode and heating mode on air conditioners when electric heat
is primary heating source. To ensure safe heater operation in heat
pump heating mode when electric heaters are energized, the ICM2
will run the higher of heat pump efficiency airflow and electric
heater airflow. The factory selection is largest heater range
approved. (See Fig. 16.)
AC/HP SIZE
The factory setting for air conditioner or heat pump size is largest
unit meant for application with model of fan coil purchased. The
installer needs to select air conditioner or heat pump size to ensure
that airflow delivered falls within proper range for size of unit
installed in all operational modes. (See Fig. 16.)
SYSTEM TYPE
The type of system must be selected.
1. AC—air conditioner
2. HP-COMFORT—provides same airflow as air conditioner
selection (approximately 375 CFM/ton)
3. HP-EFF—provides most efficient airflow for heating and
cooling modes (approximately 410 CFM/ton heating and 375
CFM/ton cooling)
The factory setting is AC. (See Fig. 16.)
