Equipment Selection And Sizing - iFlow iFLH-14000W Manual

Set Back Recovery:
If a programmable thermostat with setback is used or a sudden
increase in temperature is required, the iFLOW intelligent control
board will modulate the air handler to its maximum output to speed
temperature delivery. The next cycle will return to normal operation.
See "Heat Boost Delay" Parameter.
Test Mode:
Entering 'test mode' on the controller will allow the technician to test
the iFLOW air handler heating and cooling mode parameters. Once
completed, push the test button again to return to normal operation.
Heating:
The iFLOW air handler will automatically change the fan and pump
speeds to control the temperature output of the unit and cycle-time
length. This will allow the heat output of the air handler to match the
current heat loss of the home. Maximum 'matching' performance is
achieved when used in conjunction with the outdoor sensor. This
leads to a longer runtime, providing superior warmth and comfort.
Cooling/Dehumidifying:
The iFLOW air handler uses a modulating blower fan to regulate
humidity levels. The blower fan speed decreases in high humidity
to remove moisture quicker. The blower fan speed increases under
normal conditions to provide optimal cooling. The balance of the two
is always met. Optimal humidity levels result in increased comfort
for the homeowner, and at the same time reduces cooling loads and
operating costs.

3. Equipment selection and sizing

iFLOW air handlers are available in 3 models. Please use the
following charts to determine which best suits the application:
1. Obtain/calculate/determine a proper heat load for the home
2. Determine the inlet water temperature from water heater(or boilder)
3. Determine the duct layout/ available duct size
4. Be sure the system air flow rate matches the air flow rate of the
selected air handler
System Design Resource Note:
From the CAN/CSA-B214-12 Installation Code for Hydronic Heating
Systems, section 4.2.2.1 Heat-source output, it states: "the heat-
source output shall be not less than the heat load indicated in the
system design."
