Specification
The thermostat shall be a Robertshaw Model 300-229 or equivalent. The
thermostat shall have seven-day programmability with up to 4 time/temperature
changes per day. The thermostat will allow temporary temperature override
for a maximum of 3 hours or the next setpoint time, whichever occurs first.
The thermostat shall allow the user to program the system fan separately for
continuous or automatic operation for each of the 4 time setpoints per day
to meet local application and code requirements.
It shall be capable of operating with standard 24 VAC 2 stages of heat and
2 stages of cooling for gas, oil or electric heating and/or electric heating /cooling
systems. The thermostat shall have an electrical rating of 0.75 amp maximum load
per terminal, 3 amp total maximum load for all terminals combined. The
thermostat shall have relay outputs with standard 24 VAC control circuits and
be equipped with back-up circuitry to prevent loss of programming in memory
during power outages.
The thermostat shall have automatic changeover capability to allow the thermostat
to determine whether the heating or cooling program should be used to control
room temperature.
The thermostat shall be equipped with trouble LED’s for selectable programmed
operation. The thermostat will have an auxiliary relay coil which energizes during
the occupied periods and de-energizes during unoccupied periods.
The keypad and case shall have an integral lock to prevent tampering and/or
the altering of the program. The switching voltage shall be independent of the
heating and cooling system transformer. The thermostat will provide remote sensor
capability for up to six temperature sensors (including main thermostat sensor).
The thermostat shall be equipped with a 5-minute delay on break for compressor
short cycle protection during cooling operation to prevent compressor damage.
