Cool/Heat Min On/Off
These items are used to limit the on and off times of the cooling and heating system (in minutes).
Cool
Minimum
On
The number of minutes the thermostat forces the cooling system to remain on before turning
off. Raising this number will increase the total time the cooling system is on (saving energy),
but may allow the temperature to drift farther from setpoint (decreasing comfort). When
combined with Cool Minimum Off, cycles per hours can be obtained by using the following
calculation: 60 / (Cool Minimum On + Cool Minimum Off). The default time is 6 minutes.
Cool
Minimum
Off
The number of minutes the thermostat forces the cooling system to remain off before starting
again. Raising this number will increase the total time that the cooling system is off (saving
energy), but may allow the temperature to drift farther from the setpoint (decreasing comfort).
When combined with Cool Minimum On, cycles per hours can be obtained by using the
following calculation: 60 / (Cool Minimum On + Cool Minimum Off). The default time is 6
minutes.
Heat
Minimum
On
The number of minutes the thermostat forces the heat to remain on before turning off.
Raising this number will increase the total time the heating system is on (saving energy), but
may allow the temperature to drift farther from the setpoint (decreasing comfort). When
combined with Heat Minimum Off, cycles per hours can be obtained by using the following
calculation: 60 / (Heat Minimum On + Heat Minimum off). The default time is 6 minutes.
Heat
Minimum
Off
The number of minutes the thermostat forces the heat to remain off before starting again.
Raising this number will increase the total time that the heating system is off (saving energy),
but may allow the temperature to drift farther from the setpoint (decreasing comfort). When
combined with Heat Minimum On, cycles per hours can be obtained by using the following
calculation: 60 / (Heat Minimum On + Heat Minimum off). The default time is 6 minutes.
Stage Settings
When configured as a heat pump thermostat, by default the RC-1000 is configures for two states of heat
(auxiliary heat is included in this number). If the heat pump is not equipped with auxiliary heat, the Heat Stages
setting may be set to one (in this configuration, auxiliary will never be used).
EEC Control
The EEC Settings are used to configure Heat and Cool Energy Efficient Control and the Auxiliary Heat
Differential (when configured as a heat pump thermostat).
EEC: This item configures Energy Efficient Control (EEC). EEC continually monitors the performance of the
HVAC system and uses a PID algorithm and auto balance routine to achieve comfort while saving energy. A
setting of 0 will disable EEC. When EEC is disabled, the RC-1000 will attempt to maintain the temperature
within 0.5 degrees F of the setpoint.
A lower setting of 2-3 can be used for slow reacting sources (e.g. radiant heat) and higher setting of 7-8 for fast
reacting sources (e.g. forced air). The default setting is 5.
On heat pump systems, EEC allows the RC-1000 to use auxiliary heat only when necessary. If it determines
that the heat pump is able to heat at a rate of 5 degrees per hour or better, the auxiliary heat will not be used. If
the heat pump is unable to heat at this rate, the thermostat will use the auxiliary heat as needed. Under these
conditions, the heat pump will run continuously and the auxiliary heat will cycle on and off as needed.
