Direct Air PHRV Manual de instalação, operação e manutenção

OPERATION

(CONT'D)

PRACTICAL

TIPS

To avoid window condensation:

• It is not necessary to

change the humidity control

every day. Monitor the

average weekly

temperature or experiment

with various settings until

you find a level that is

comfortable for you. Adjust

the control when needed.

NOTE:

A dehumidistat is ideal for

use in energy efficient

houses where indoor

humidity (during the

heating season) is higher

than outdoor levels. High

humidity is a major cause

of structure damage and

IAQ problems such as mold

and mildew.

PRACTICAL

TIPS

NOTE:

When an Intellitek control

is installed, the rocker

switch located on the right

hand side of the HRV will

be automatically

deactivated giving the user

complete control from

wherever he/she wishes to

mount the control pad.

NOTE:

The override speed cannot

be set at a fan speed lower

or equal to the normal

operating fan speed. For

example, if the unit is

normally operating at a

medium fan speed, the

override fan speed will be

automatically set to high.

NOTE:

5MR model, changing the

override speed will change

default override speed for

other external controls.

EXAMPLES:

If on the 5MR control, you

have set the override

control at medium, and

you start an external

remote control (15 min.

timer), the unit will run at

medium speed for 15 min.

OPTIONAL REMOTE CONTROLS

Dehumidistat I - The wall mount dehumidistat monitors the humidity level in

2 wire

installation

the area it is installed. When the humidity level rises above the desired set-

point, the HRV will activate to high speed/override mode. Once the humidity

level returns to desired condition, the unit will return to the normal mode.

Dehumidistat II - The wall mount dehumidistat II offers the same features of

4 wire

installation

the dehumidistat I plus additional off/on control for the HRV. Dial illuminates

when in override mode.

RTS 3 - The RTS 3 is designed to provide an intermittent boost to the Heat/Energy

3 wire

installation

recovery ventilator. Depressing the fan control button will energize the HRV/ERV

system into high speed from a low or standby mode. The ventilator can be set to

continue on high for 20, 40, or 60 minutes by pressing the control button one, two

or three times. Pressing the button a fourth time will cancel the timing function.

EDF 1 - The EDF 1 is designed to provide 3 modes of operation to the Heat/Energy

2 wire

recovery ventilator. Pressing the "Push" button once initiates the unit to run at a

installation

continuous low speed of operation (green). Depressing the button twice allows the

ventilator to run for 20 minutes and then turns off for 40 minutes (yellow). Touch

the button a third time and the system will run continuous on high (red). The ven-

tilation system will stay on the last function selected until it is changed.

15-min Timer - The 15-minute remote timer is typically installed in areas

where contaminated such as moisture and odors, are produced. Simply push

the button and the HRV will activate to high speed for 15 minutes. Up to 5

electronic timers can be installed throughout the building at a distance of up

to 500 feet (152 meters) from the HRV.
