Dehumidistat Control

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY

BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE

PERSONAL INJURY AND/OR PROPERTY DAMAGE.

DESCRIPTION

These wall-mounted, line or low voltage humidity controls

are available as a Humidistat commonly used to control

and operate a furnace humidifier or as a Dehumidistat

commonly used to cycle an air conditioning system to

control humidity in an unoccupied home to prevent mil-

dew build-up associated with high humidity levels.

These humidity controls feature a moisture-sensitive

nylon sensing element and also provide positive ON-OFF

settings for manual operation.

Operator: Save these instructions for future use!

If in doubt about whether your wiring is line, or low voltage,

have it inspected by a qualified heating and air condition-

ing contractor, electrician, or someone familiar with basic

electricity and wiring.

Do not exceed the specification ratings.

All wiring must conform to local and national electrical

codes and ordinances.

PRECAUTIONS

This control is a precision instrument, and should be

handled carefully. Rough handling or distorting compo-

nents could cause the control to malfunction.

To prevent electrical shock and/or equipment dam-

age, disconnect electric power to system, at main

fuse or circuit breaker box, until installation is

complete.

Do not short out terminals on primary control to

test. Short or incorrect wiring will burn out humid-

ity control and could cause personal injury and/or

property damage.

2274W

CAUTION

Do not use on circuits exceeding the rated volt-

age. Higher voltage will damage control and could

cause shock or fire hazard.

ATTACHING HUMIDITY CONTROL TO ELECTRICAL BOX 1. With wallplate still attached to humidity control and wires through wallplate, connect leads together; one black to Line, other black to Load and secure with wire nuts. Connect green wire to electrical box ground. (see Fig. 2) 2. Remove the two screws from the humidity control cover and separate the humidity control from wallplate by gripping the wallplate in one hand. Use the other hand to pull gently at the top and bottom of the humidity control. 3.

SETTING & ADJUSTMENT DEHUMIDISTAT CONTROL A dehumidistat wired in parallel may be used to maintain the relative humidity level during unoccupied times regardless of ambient temperature. By cycling an air conditioning system the relative humidity is maintained to help prevent high humidity levels which are associated with mold and mildew build-up. 1. A relative humidity environment of 50-55% is desirable during the summer.

MONTAGE DE LA COMMANDE DANS LA BOÎTE DE RACCORDEMENT 1. Pendant que la commande est encore montée sur le socle, par lequel passent les fils, exécutez ainsi les raccordements:un fil noir sur le secteur, l'autre sur la charge, en prenant soin de les relier à l'aide de marettes. Raccordez le fil vert sur la prise de terre de la boîte de raccordement (voir la figure 10). 2.

Pour obtenir ce taux, régler le thermostat de climatisation à un point de consigne supérieur à la température d'occupation ou l'arrêter. La commande de déshumidification commandera au besoin la mise en marche du système de climatisation de manière à maintenir le taux d'humidité ambiante choisi. 2.
