Summary

Controller Functions and Display

Temperature Control

Maintains setpoint via valve/compressor commands. Can use external sensor.

Display

Shows room/return air temp or setpoint. Displays heating/cooling status.

Operating Modes and Control Sequences

Normal Operation

Maintains setpoint, allows manual fan speed adjustment. Setpoint range can be limited.

Auto Timer Mode

Automatically switches between Normal and Energy Saving modes based on timers.

Energy Saving Mode

Uses preprogrammed timers for energy saving. Setpoints adjustable via control parameters.

Standby Mode

Maintains heating/cooling setpoints. Factory setting is OFF.

Avoiding Moisture Damage

Fan can run continuously at minimum speed to prevent moisture damage in warm climates.

Water-Based Fan Coil Application

Used with a valve for heating/cooling, heating only, or cooling only.

Compressor Based Application

Used with a 1-stage compressor for cooling only or heating only.

HeatingCooling Mode Changeover

Details automatic/manual changeover for RDF210 and RDF210.2.

Minimum Output Time Y11

Minimum on/off times for output Y11 can be adjusted (1-10 mins).

Fan Operation

Ventilation Always On

Fan control can be set to 'Temperature-independent' for continuous ventilation.

Dwelling Time

Automatic fan speed dwelling time (2 mins factory) can be adjusted (1-5 mins).

Fan in Auto Timer Mode

Default fan mode is automatic; can be changed to manual. Returns to auto on mode change.

Auto Timer Programming

Setting the Timers

Instructions for setting up 8 programmable timers for Auto Timer mode.

Viewing the Timers

Review the 8 programmable timers sequentially.

Default Timer Settings

Shows default timer settings for A1-A4; A5-A8 are free.

Reloading Default Settings

Procedure to reload default timer settings.

Overlapping Timer Sequences

Explains how overlapping timer sequences result in an OR combination.

7-Day Time Clock

Setting the Time Clock

Instructions for setting the 12/24 hour format, time, and weekday.

Power Failure Handling

How the clock handles power failures and time synchronization.

External Sensor Input B1-M

Automatic HeatingCooling Changeover

Explains sensor input B1-M for auto H/C changeover using water temp.

Remote HeatingCooling Changeover

Describes using an external switch for manual remote heating/cooling changeover.

External Room or Return Air Sensor

Details using B1-M for external room or return air temperature sensors.

Summary of B1-M and P22

Table summarizing P22, B1-M, and controller variables for temperature maintenance.

Error Handling

Temperature Out of Range

How display shows limiting temps when actual temp is out of measuring range.

External Sensor Failure

Controller switches to internal sensor on external sensor failure; displays 'Err' if both fail.

Infrared Remote Control
