Call for Auxiliary Heat (24 VAC @ W2): When calling, furnace will provide heat at a stage 10 output rate. With a call for

auxiliary heating the Matrix will function as a single stage, full fire appliance. This means the burner will come on with a

thermostat call and go off when the call is satisfied. If HRV set to ‘ON’, HRV will operate at the low (continuous) ventilation rate.

Outdoor Sensor: The auxiliary heating function

(24VAC @ W2) will utilize the outdoor sensor if available.

The outdoor reset function is not used for W1 heating. This

function is also active during a hydronic heat demand

(24VAC @ H).

Plenum Sensor: The Matrix is equipped with a plenum

temperature sensor that must be field installed in the supply

plenum and wired to the furnaces external terminal strip.

When installed the Matrix fan control displays the plenum

temperature and will use it to detect problems in the supply

of heat to the space.

Call for Circulating Fan (24VAC @ G): Matrix

operates at the minimum air circulation rate for the heat

profile selected (300/400/500 CFM). If HRV is set to ‘ON’

(See 8.2 Fan Controller), the HRV will ventilate at the low

(Continuous) ventilation rate.

Call for Dehumidification (24VAC @ DH): Matrix

operates at the minimum air circulation rate for the heat

profile selected (300/400/500 CFM). HRV will ventilate at

the high (Override) ventilation rate.

Call for Cooling Fan (24VAC @ Y): Matrix operates at the prescribed air circulation rate (COOx10 CFM – See 8.2 Fan

Control). HRV will not operate during a call for cooling unless there is a concurrent call for DH – Dehumidification or G –

Continuous and HRV is set to ON.

10.2 Duct Sizing

When sizing ductwork, a maximum flow velocity of 800 fpm is

desired. Table 11 shows common duct sizes at specified flows. The

maximum flows that can be expected are shown in Table 10.3. It is

important to maintain the return plenum pressure as low as possible.

Keeping this ductwork as free flowing as possible will offer more

supply static pressure to overcome A/C coils, closed registers etc while

mai ntaini ng cons tant flow.

Any additional filtration, humidification, or de-humidification

equipment should be installed external to the return or supply ducts so

not to create additional restriction.

Example #1

No cooling function with Heating

profile of PF2 selected. Maximum airflow will be

Example #2 Cooling set to 800 cfm for 2 tons of

cooling with Heating profile of PF3 selected.

Maximum airflow will be greater of cooling or heating

function. Maximum 1200 cfm.

*Measured from return plenum to supply plenum prior to A/C coil.

ECM motor can produce near constant flow provided horsepower or

maximum speed of motor is not exceeded.
