Robertshaw 9801i manual

If the LO BAT signal is flashing, or the thermostat display is blank, batteries may need to be replaced. If the thermostat does not follow the program entered during installation, the user should check the program to confirm that the thermostat is set to COOL or HEAT.

Simple Science: Quantum Physics, Explained. What Is the Federal Minimum Wage? During a set back period or set up in cooling , it allows the thermostat to look up to two hours ahead to determine when to turn on the heating cooling system.

During this time period, the second stage is locked out to allow the first and most efficient stage to bring your home to the desired temperature.

Your thermostat automatically retains the time of day for approxi- mately two hours in the event of a power outage. Is there anything I can do? Page 28 The manufacturer warrants to the original contractor installer or to the original consumer user, each new Robertshaw thermostat to be free from defects in materials and workmanship under normal use and service for a period of two 2 years from the date of purchase.

In most cases it is better to slightly undersize than oversize. Extra consideration should be given in applications that require large amounts of cooling in cold weather, such as buildings with a center or core area. Hot gas bypass should be considered on some commercial systems.

If the HVAC unit is supplied with an economizer, it is recommended that the economizer package be equipped with a relief air damper. The SlimZone Classic requires the use of motorized zone dampers, such as the A 24VAC 2 wire powered closed, spring open or 3 wire powered closed, powered open configuration. The pressure drop across typical zone dampers is negligible and normally not a factor when sizing or calculating branch duct CFM.

Typical zone control dampers are designed to work only with low pressure systems 1. Balancing dampers should be installed ahead of all motorized zone dampers. Zone dampers should be installed 10ft.

Flex or lined duct is recommended on the last 5ft. A bypass damper must be installed on all systems of three 3 zones. Some two 2 zone systems may require a bypass damper. The thermostats and motorized dampers may be located up to ft. Do not use heat pump thermostats because a call for compressor from the thermostats will be recognized by the panel as a cool only call. The control algorithm in this panel is configured such that heat pump thermostats are not required. The mode of equipment operation at the control panel is first determined by the signals present on the C and H input terminals of Zone 1, then on the mode of operation of the zone thermostat s.

To comply with Class 2 wiring code, the maximum load allowed to be switched by the output terminals is 2. All outputs are protected by a current limiting device. System wires should be tagged to match the panel terminal designations. All zones served by a panel should have the same basic load characteristics. References to typical dampers in this manual are Robertshaw model dampers. The basic system consists of the main SlimZone Classic control panel and the components required to support it.
