TB7100A1000 MULTIPRO™ MULTISPEED AND MULTIPURPOSE THERMOSTAT

SEQUENCE OF OPERATIONS

The heating and cooling setpoints shall be individually adjustable for both the Occupied and Unoccupied periods. The thermostat
shall have a minimum deadband of 2°F (no mechanical heating or cooling shall operate within this deadband). Space
temperature deviation above the cooling setpoint or below the heating setpoint shall generate a demand signal to control the
system as follows:

A. HEATING: The thermostat shall control the heating output based on the demand signal communicated from

the thermostat program, taking into account both space temperature deviation (proportional
gain), the duration of that temperature deviation (integral gain).
The thermostat shall energize heating equipment when space temperature falls below heating
setpoint.

B. COOLING: The thermostat shall control the cooling output based on the demand signal communicated from

the thermostat program, taking into account both space temperature deviation (proportional
gain), the duration of that temperature deviation (integral gain).
The thermostat shall energize cooling equipment when space temperature exceeds cooling
setpoint.

FROM UNOCCUPIED
TO OCCUPIED:

E. FAN OPERATION: For Heat pump or Conventional modes:

Initiation of heating setback or cooling setup for each of 7 days shall be provided by a
programmed time schedule manually entered into the thermostat. When all or a portion of a
manually programmed schedule is unavailable, the thermostat shall control to the default
program as shown in Table 1.

Table 1. Default Program.

Heating Setpoints 70°F (21°C) 55°F (13°C)

Cooling Setpoints 75°F (24°C) 85°F (29°C)

The thermostat shall incorporate a ramping feature that gradually changes the space setpoints.
During recovery operation, the setpoint changes at a rate in degrees per hour (defined in the
Installer Setup Menu).

a. On: Fan operates continuously in Occupied mode, and during a call for heat or cool in

the Unoccupied mode. Uses the G fan relay.

b. Auto: Fan is energized with calls for heating and cooling. Uses the G fan relay.

For PTAC and Fan coil modes:

a. Lo, Med, Hi (Fan Coil), Lo, Hi (PTAC): Fan operates continuously in Occupied mode,

and during a call for heat or cool in the Unoccupied mode. Uses the G, G2, G3, fan
relays.

b. Auto: Fan is energized with calls for heating and cooling. Auto uses the fan ramping

algorithm to automatically select the correct fan speed

c. PTAC and Fan Coil modes can be configured for Auto only, constant fan speed only

(Lo, Med, Hi), or both.

d. Auto Fan Reset: Set the fan from a constant fan speed (Lo, Med, Hi) to Auto after 2 or

4 hour time period. Saves energy and fan usage. (optional feature)

a. On loss of power, the thermostat shall maintain programmed times and temperatures

for 10 years.

b. Clock and day information shall be retained for a minimum of 2 years.

b. The Holiday Override shall fix the schedule to operate in Unoccupied mode for a num-

ber of days (between 1 and 365) without changing programming saved in memory.

c. Pressing “Cancel” or “Run Schedule” shall cancel the overrides and return to the

program.

d. Remote Setback input terminals can be used to operate the thermostat in either Occu-

pied or Unoccupied mode (non-programmable mode only).
