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."

4.2.2.2 Dual-purpose water heater
