Coster RTE 982 Quick Start Manual

WEATHER COMPENSATOR
FOR CONTROL OF VALVE OR BURNER
RTE 98.
Eng.
• Analogue controller for boiler plant:
– 1 modulating or On-Off output for control valve or burner
– 1 On-Off output for control pump or burner in relation to programmed times
– voltage-free output contacts
– adjustment of heating curve to compensate for weather variations in intermediate seasons
– possibility of adjusting value of desired ambient temperature by remote control
• Power supply 230 V~; installation on 144 x 144 control panel back plate

1. APPLICATION

RTE 98. controller is designed for winter compensated control in medium and large central heating plants for
premises such as:
– administrative and commercial centres
– schools and public buildings
– apartment blocks
It is suitable for all climatic zones and for any type of heating media:
– panels
– radiators
– fan coils
RTE 98. controls mixing or diverting valves operated by reversible electric actuators with three-wire control and
opening times of from 90 to 630 seconds, or the boiler burner.

2. FUNCTIONS

The main functions of RTE 98. are:
• Winter regulation of the flow temperature in relation to the outside temperature with:
– PI control action
– adjustment of heating curve to compensate for weather variations in intermediate seasons
• Modulating three-wire control or On-Off
• Control plant pump from timed programme in use
• Timed programming: 24-hour (RTE 982) or 7-day (RTE 983)
• Remote control for adjusting temperature programmed on controller
• Timed control : RTE 98 is able to control an On-Off output which operates with the program times used. It can be
used for the control of the plant circulation pump : in the Normal "Sun" periods contacts 8-10 are closed, while in
the Setback "Moon" periods contacts 8-10 are open.
