ASYSTAT605 HEAT/COOLING THERMOSTAT

LOCATION

Locate the thermostat on an inside wall, since the temperature

of an outside wall varies with outdoor conditions.

The position on the inside wall should not be less than 18 inches

from the junction of an outside wall.

The vertical location should be between three and five feet above

the floor. The lower mounting has the advantage of being more

nearly in the zone of occupancy but is subject to furniture inter-

ference and to tampering by children.

The location should permit a free flow of air over the thermo-

stat.

Having made a tentative selection of the best mounting location,

check against the following possible objections:

1. Steam pipes, water pipes or warm-air stacks in adjacent

partition space;

2. Cold, unused room on opposite side of partition;

3. Kitchen range on opposite side of partition;

4. Subject to radiation from fireplace or direct sun effect from

windows;

5. Subject to drafts from stairwells or outside doors;

6. In direct path of air currents from radiators or air delivery

registers;

7. Heat from nearby table or floor lamps or television receiver.

INSTALLER'S GUIDE

MOUNTING AND WIRING

Having selected the most desirable location, proceed with mount-

ing and wiring as follows:

1. Pull cover from thermostat.

2. Remove the thermostat from the sub-base by loosening the

four screws. See Figure 1.

3. Mark the two desired mounting holes and the cable hole, us-

ing the subbase as a template.

It is recommended that the holes marked "B" be used for stud

mounting and the holes marked "C" be used for normal wall

mounting. See Figure 2.

4. Drill the three holes previously marked on the wall.

5. Make the connections to the thermostat sub-base in accor-

dance with the color code and the wiring diagram that applies.

See mounting instructions, Figure 2, and system wiring diagram,

Figure 3.

6. Fasten the sub-base to the wall with wood screws provided.

Push excess cable back into wall and PLUG WALL OPENINGS

WITH PUTTY OR CAULKING COMPOUND to prevent

drafts from affecting thermostat. Replace the thermostat on the

sub-base. MAKE SURE THAT ALL FOUR SCREWS ARE

TIGHT.

7. Replace cover on thermostat.

8. Wiring must comply with local electrical codes and such

National Codes as apply.

ADJUSTABLE HEAT ANTICIPATOR

The heat anticipator in the thermostat is adjustable to the control

circuit current and is mounted in the thermostat as shown in

Figure 1. The current range is marked on the carton label.

To select the proper amount of heat anticipation, move the slider

on the anticipator assembly to the number on the scale corre-

sponding to the control circuit current of the primary control,

gas valve, or heating relay.
